Seiko 6105 "Captain Willard" Vintage Watch Restoration

[@G-regular503]

I remember in high school everyone wanted a Seiko. I've always wanted one with the glass back so you can see the movement. Another killer video.

[@larsfrandsen2501]

I love the fact that you don't have music in these videos. Great instructional videos!

[@danmason6116]

Yeah that would totally ruin the video

[@AllanO808]

YES! It's much better for me, as I'm profoundly deaf and rely on the subtitles, but it is still lovely to hear that calm voice, even though I still need subs to fully understand. I absolutely hate the other channels, which are just silent and no subtitles I refuse to waste my time on them

[@tomhill4003]

No music needed! Marshall is an accidental ASMR for gearheads and watch enthusiasts. His voice is so soothing.

[@BrotherClint-eg7vf]

I like how u included showing your mistakes and corrections. It's honest and encouraging for beginners in the hobby that they aren't the only ones messing up occassionally.

[@cartoonsbyjohn]

I bought this exact watch in the Navy also overseas during the Vietnam era in the Pacific exchange for about $45 at the time. I have used this rugged watch high diving and skin diving, maintenance aircraft duty on the flight decks of aircraft carriers and has been through hell and back, dropped and banged up numerous times and just keeps on ticking. It does lose a few minutes a day but I can get that service again. I was curious in watching you doing the disassembly on components this watch to confirm it’s durability. Brings back lots of exciting memories. Glad you also enjoy this watch too and thanks for sharing.

[@claudea79]

Great video, Marshall! Certain parts (wheels) are made from special reinforced plastics (Composites) to minimize/eliminate the need for lubricant, thereby reducing the overall lubricant used. Excess lube will find its way where it is detrimental to the movement.

[@nunchaks700]

Seiko definitely does it better than Tissot

[@zawzawaung6789]

For American GI's in Asia, this watch was known as the "poor man's Rolex Submariner". It started in the early 1960s when Special Forces guys and other troops were serving in small batches in Vietnam and Laos, on an unusual arrangement where they collected a lot of money in per diems. Jewelers in Bangkok and Saigin made a pile selling them Rolexes and star sapphire rings, and these became the 'in' accessories. Later the Seikos became popular with GIs because besides being cheap, they were dependable and not so expensive that losing one would be a major hit. Some guys would sharpen the edge of the bezel to a razor edge for fighting; a backhand across the face with the bezel would cut a face to the bone, allow for lots of dramatic bloodshed. The bezel ring could also be used as a pace counter when doing dead reckoning navigation in the jungle, one click for every hundred meters. Could be used for measuring burn rate on time fuse...a million handle things about the click bezel.

[@WristwatchRevival]

Wow, that really brings these tools into focus for the people who actually used them! Thanks for the info.

[@andysmith1996]

Sharpening the bezel to a razor-edge sounds like an urban myth - first, it's on your wrist, not the back of your hand, so it would be difficult to back-hand someone with the bezel and, second, if it's that sharp, you've just made your bezel unusable for anything except cutting. You'd cut yourself if you tried to use it to time anything and possibly even if you were just adjusting the time. Good story, though.

[@zawzawaung6789]

@@andysmith1996 The first time I bought one of these in the PX in Korea it was $35 all-in. Believe me we had a unit full of absolute nutters; sharpening the bezel was not actually necessary to open up cheeks and forehead in a dust-up, but idiots did it anyway. Another popular use for the bezel was timing time fuse burn for demo. The G-shock kind of unseated the Seiko as the go-to field watch.

Hey there. I have been following you for about a month and your videos are awesome. Educative and your narration style makes it easy to go through the 50 odd minutes. I'm an engineer and love these watches. There are engineering marvels. I have read through a couple of pages of comments and didn't see anyone give you an answer regarding the plastic gear, so here it goes :) . Plastic gear ( especially POM-Polyoxymethylene, Polyacteal or plain acetyl or Derlin) are used because this material is self lubricating and strong. Also dampens some vibrations if vibrations are a thing in that particular area and are a lot quieter when running. Also in some cases if thermal expansion is an issue, plastic gears minimize this issue. I know plastic is considered a "cheap" solution, but manufacturing a plastic gear so small with the required dimensional accuracy ( that is required in a mechanism like this) is quite difficult and expensive. Hope this helps. Keep up the great work. Cheers.

[@flyingphotography5770]

@ Pascal G Thank you. I had a hunch the plastic is self-lubricating. Japanese discipline eschews cheap for imagined cost savings. Bean counters in Japan do not enjoy the status nor importance of American and western accountants. The rich history of Seiko, their ability to innovate, and their cultural ideology keeps Seiko as a force to contend with. The 7S26 movement, for example, is decades old, and is a tank in endurance. Yeah, no, plastic is not cost saving, it is ingenious.

[@babist4852]

@@flyingphotography5770 Yes Exactly! Good Engineering and Innovation uses the "best" materials for each situation. An extremity of this is Aerospace and F1 cars! In these two cost is no issue, but in everyday products you innovate to give the best solution within a budget. Cheers!

[@mathete9968]

This is the reply I was waiting for. I wondered about the gear material also. I have a background in both university engineering and much more so, university science, as well as engineering trades.. I remember learning about properties of metal and metal alloy materials and how they interact to enhance minimal wear characteristics, So I an unsurprised by your comments on the use of a polymer for its lubricant properties . Totally agree about his voice and ability as a presenter. He reminds me very much of a Professor of Hebrew named Allan P Ross. Professor Ross has a voice and manner EXACTLY like this man and he is also very rast to listen to and learn from. Very gifted individuals

[@LaurentiusTriarius]

Derlin is such a wonder material. It's also less brittle than the hardened metal gears, nobody likes to break a tooth.

[@TOMKATPEDALS]

I believe the plastic was also more forgiving if the quick set date was adjusted too close to midnight and wouldn’t ruin the date mechanism as easily.

[@retourmoto]

I don't even like watches that much, but this is the 16th video from you that I'm watching, it's such a nice experience with you explaining everything and give like a little tour to the viewer about watchmaking...can't really explain it but it's so nice that I just sit down and watch 2-3 in a row easily. Thank you for such nice content.

[@geoffreycarter3981]

Thanks for sharing! I was given a 6105-8009 which is very similar to this (from c.1970) by my father who's father was career US Navy and bought it originally on the Navy Exchange in Honolulu. He gave it to my dad who wore it half his life and then gave it to me for my 16th birthday. I found the classic "waffle strap" is the way to go if you're not going the NATO strap route. An exceptional watch! My other grandfather was career British Army and I have his Smiths W10 as well which I cherish. It's so neat to have watches from both my grandfathers now they are both gone. I've worn them both through my 20s and plan to keep them forever and pass them to my son one day. I've added a modern seiko diver which I can actually take in the pool and ocean and nice Seiko 6R15-00C1 to complement the collection

[@andrewclarkehomeimprovement]

Really interesting one and thanks for the background. I really appreciate your honesty in not editing out where it doesn't quite go right. Thanks again.

[@bigmikeh5827]

As a young airborne soldier stationed in Alaska in the early 80s this seiko was the mark of a professional NCO. Came back from a deployment to Ft Sherman, panama and had one wrapped waiting for me. My wife found out I had been selected for promotion to Sergeant. Wore it daily for about 10 years. The time hack was critical for setting the time on our cryptographic radio sets. My youngest son wears it now. The G-shock was more popular after the 80s. A great watch for an Airborne Ranger. ⛩ Thank you for the video. Great technique on your presentation.

There are always ways to get out of any holes you fall down, and 3. It's not "stupidity", just lack of experience! Thank you for sharing that we ALL make mistakes when we are learning!

[@medea27]

A truly iconic watch 👌Others have mentioned the benefits of a 4 o'clock crown avoiding catching on clothing, but it's more about _accessibility..._ it enables divers (and soldiers) to easily change/set the time while it's still on your wrist _and_ when using gloves (big fingers can manipulate it without your wrist or the cuff of wetsuits/gloves/shirts/etc getting in the way, like it does with a 3 o'clock crown). And those huge boxes instead of numbers are much easier to see through a facemask at 20m deep, leaving the numbers for the bezel functions. I love watches that are pure function first & form second, and this Seiko is exactly that.

[@MorellioBenoir]

Built to be serviced is such a wonderful and overlooked thing a lot of times. Anything that you do professionally should be easy for a novice or journeyman to take over. Design can be beautiful and unique, and in that uniqueness, draw the next person in to want to work on it. That's the best message from designer to observer. Love. :)

Quickset calendar and hacking in a 1960's watch? Seiko was most definitely ahead of its time. The more I learn about the brand the more I love it!

And they came out with the first quartz around that time too. They were definitely not slacking. Wonder if the fact that there were two competing Seikos within the umbrella brand (Daini and Suwa) was responsible for that

For loading the mainspring into the barrel from the preloaded washer, find a decent wood screw with a flat head about the size of the ID of the MS washer and use that to push the spring into the barrel vs using your tweezers.

The reason for the 4 o'clock crown is to keep it from digging into your hand when you bend your hand upwards while doing things like diving or being in combat. It's a lot more comfortable for wearing while being active in that way. Some other dive watches put the crown on the left instead. I prefer the 4 o'clock solution.

Hey, there, Marshall! Relatively new viewer and subscriber, and I'm totally loving watching you work! I did have one minor request. While you do a fantastic job showing us disassembly and assembly, I was hoping you might show us a bit of calibration with the timing machine when you have a watch that you want to adjust when it's losing time. I presume it has to do with that little fork above the balance that has the little inscribed gradations. Anyhow, just a small thing. Keep up the great work.

[@AudioFlat]

The use of plastic gears is very interesting (to me anyway ;)). Cost will not be the issue as material cost is almost inconsequential for such small parts and producing tiny components from plastic is actually much more difficult than you would think. I suspect the reason it is done is because plastics like Nylon have self lubricating properties.

[@SgtMacska]

That is what I’ve heard too. The plastic parts don’t need publication so the watch can go longer without a service. But I don’t know if the parts that are plastic in this Seiko movement are in particularly high-friction places.

[@Mr2handyandy]

As already mentioned plastic should have a lower coefficient of friction but also won’t tarnish/corrode over time. Also probably lighter which I would think improves efficiency.

[@Bob.martens]

This is one of the last Seiko's where the crown is actually at 4 o'clock. All modern ones are at 3:47 to have the standard date wheel on any movement interchangable between 3 and '4' o'clock cases. The otherwise almost perfect reissue SLA033-crown is at 4:10, for the same reason. Seiko were too cheap to print a custom datewheel for 4K.

Interesting, I never knew that, thanks for sharing!

[@ronnied13]

[@jimstanley_49]

I would imagine that they did indeed go searching for parts they could convert to plastic for cost savings, and then only do it to those few parts that were truly non-critical. Some of the calendar parts sound like good candidates. Only have to turn once a day, fine timing isn't needed...

[@YourOldDog]

The plastic parts are to reduce wear on the day/date change.

[@SlapShotRegatta22]

Hmmmm, interesting. I don't doubt it by any means but why wouldn't they use plastic parts for other high-wear areas? There has to be other mechanisms of the watch that could benefit from reduced wear. Is there something specific to the date works that predisposes it to higher wear than other areas?

[@21asds]

@@SlapShotRegatta22 I'm not quite sure myself, I read somewhere that those wheels are not under a lot of stress, plastic is more flexible so it could help prevent accidentally damaging the wheel if you change the date at midnight, or maybe it's just a way to reduce production cost.

Hi, Marshall -- drafting on MTG Arena and listening to your watch video voiceover on a quiet Saturday night. Thanks.

[@troynasello2085]

You're not gonna change the gasket in the crown? From what I've seen it's a pain in the ass, gotta disassemble and rebuild the crown assembly. But important for water resistance.

[@WristwatchRevival]

Yeah I didn't find one in time for the video, and I also haven't done that before. I'll try to track a new one down and replace it.

[@carywatmore]

Just found this channel and fantastic to see this and much respect for the knowledge and skill

[@MMitchellMarmel]

I'm wondering if the plastic bits are either a) self lubricating or b) anti-magnetic?

[@troynasello2085]

So seiko could save a couple pennies per unit. Only thing that needs to be antimagnetic is the balance.

[@RedWolfRedWolfRedWolf]

The first swiss Quartz calibre the 35x series had a Teflon gear and that was definitely not made for cost cutting. I wouldn’t be surprised if that part in this seiko was actually Teflon.

[@Andrew.W75]

I think they were meant to be self lubricating & are not under stress so can be made plastic!

[@MrGrentch]

@@RedWolfRedWolfRedWolf If you're referring to the Girard Perregaux(with input from JLC) calibres, they had teflon bearings instead of jewels, an effort to reduce maintenance. And it worked very well, though people were and are hung up on "jewels" sounding luxurious so it never caught on. I've a few of those watches and a couple were sold as not working and on closer inspection I found someone had oiled those teflon bearings during their lifetime.(the JLC designed "maintenance free" date mech is one of their weak points). Removed the oil and off they ran. It wasn't the first Swiss quartz wristwatch calibre in the wild either. That would be the Beta 21 series and the Longines UltraQuartz(have one of them too. Insane design :) ). The GP 350 series were the first to use the 32768 Hz frequency that the vast majority use down to today(their stepping motor design was superior too, but didn't catch on, likely because of cost).

Great to see a 6105 brought back to working condition. I have a 6309-7050 from 1984 that runs like a champ, though I always loved the 6105 case. Sadly that design got popular and is no longer affordable. Seiko has reissued a similar design, and I may get one! BTW - Years ago, I purchased a new RADO 2836 movement for use in a project. The movement was brand new stock purchased at a time when you could buy Swiss movements without the whole watch. Due to some unfortunate incidents with less than reputable watch makers, I have been unable to do anything with that movement. I believe the keyless works may be jammed or some other misfortune occured in the hands of others. I tried repairing the movement myself, but I'm more comfortable with older more sturdy Seiko movements. In other words, I got it somewhat apart, and gave up. There were a few missing screws, which were a result of the previous people who I mistakenly entrusted with the movement. So, now I have this nice movement, a bunch of other parts (I assume they belong with the movement). I'd like to send it to someone who can give it life again, or a student that can practice with it. I just don't want to see it stay in this condition. Would you like it, or know someone who would want it? I'd be happy to pack it off, and give it another chance. Thanks!

November, 1974 is the manufacture date of this watch. The serial number on the caseback tells that.

[@crbswiss]

The date on the back of the dial is October of the same year

[@troynasello2085]

Was it? It could a been, I may have remembered it wrong. Wait, you said dial. Ok. The dials were commonly made a month before or sometimes even after the case was manufactured in the factory. It's actually rare to see them from the same month. I was going from the caseback at the beginning of the video. It read 4N

[@troynasello2085]

Ok, I just watched it again and the first 2 entries on the serial number are 4N. Just to explain for those who don't know, because I realize you know how to read the dates; So that means 1974 & November. The first digit is the year in the decade and the second is the month, but it's usually a number. 1 is January, 2 is February, 3vis March, etc. But because the last 3 months are represented by 2 digits such as 10 for October, 11 for November And 12 for December, seiko used the first letter of the name of the month for these last 3 months of the calendar to reduce confusion. The serial number on the back of this 6106-8110 clearly started with 4N.

[@crbswiss]

@@troynasello2085 I wasn't trying to say you were wrong, in fact the dial being produced in October would reinforce your comment. From what little i know about this, mostly watching Spencer Klein videos and a little of my own research into my 6309-7040, the dial was often dated from the month before the caseback date.

[@Andrew.W75]

A lot of people here who watch Spencer Klein lol including me!

[@comicandothercons658]

another great video of yours with my dinner! 😊 also, thank you so much for explaining when you made a mistake, what did it cause, why you made the changes and what it does. that means the world to us, that's how we learn, by someone saying i made a mistake, explaining said mistake and what they did to fix it. thank you so much for that. 🙏😉

[@nickmorrell385]

you sound like seth rogan... i lvoe it! sub'd!

[@anthonytindle13]

Thankyou for these uploads of yours gents wristwatches and the repair are something that's fascinated me for as long as I've been able to read and write this is a hobby I wouldn't mind now I'm creeping up to the retirement years I can do it indoors and it's relaxing for. me the patience side is nothing as it's something I have in abundance I really enjoy watching you with this pastime thankyou and thoroughly enjoy viewing you with the craft. Great. work Marshal I've learned a lo from you.

[@michaeljasminestewart1618]

I like the vids but wow a little overkill on the ads.

[@WristwatchRevival]

Yeah sorry, I went in and trimmed a couple of them out. They were auto-added in. These videos take a ton of time and money to make and I don't currently make anything from them besides the small amount you get from ads, so it's a hard balance to find right now. Hopefully taking a few out helps. Thanks for watching!

[@AhuCJ]

Wristwatch Revival I find mind the ads at all king. Keep it going

[@cristobalosuna3106]

You have a very natural, informal style that makes it very pleasant to follow your videos. Also, very good tools for a non professional watchmaker... I am officially jealous. Keep up with the good videos!

[@WristwatchRevival]

Thank you :) And yes I have built up my tools over the last few years, I try to save and buy better ones now after trying a bunch of cheap ones and not liking them.
