[@michaelriera6277]

This is easy. If you’ve purchased your watch within the last 15 years you do Not need to service at any set intervals especially if the watch is not worn everyday and is part of a larger rotation. Newer watches use synthetic oils that do not gunk up, degrade, or evaporate like older mineral oils. Periodically check them on a timegrapher and if the amplitude is between 230-315, small beat error, not running too fast or too slow then there is absolutely No reason to submit the watch to an intervention that may ultimately introduce issues that were not originally there.

[@Mark-lj1dj]

I completely agree. I have a Seamaster and due to the coaxial escapement I'm just going to wear it until it starts losing or gaining time excessively. The only other logical reason to service regularly is the waterproof seals might need replacing.

[@SupperUpper]

More than one experienced salesperson told me over the past 30 years: As long as it runs within a couple of seconds a day, let it run, it’s fine. This was reg Rolex watches and in the 90s and 2000s

[@infooptimalfitness7720]

@@Mark-lj1dj Agree... Run it till it stops. The only reason to service is to put in new seals if you want to go swimming. My Seamaster is 16 years old, never serviced and keeps perfect time.

[@bigc208]

That’s my attitude. Serviced my Rolex GMTII after 6 years and after it came back the hour hand started dragging the dial a bit and left a fine mark. Took a while to notice. After that was fixed I waited until the crown started getting stuck and the watch stopped running. That was 20 years later. I have 8 self winding watches that I treat the same way. A 2006 Submariner and 2008 Daytona that have never been serviced, run as good as the day I bought them. I don’t dive with my mechanical watches so no worries about the seal not keeping the water out at 200m depth. At $600-$1500 for servicing I better have a good reason. As far as accuracy, if they’re running within spec I’m happy. Besides, if I need to know to the second what time it is I use my phone.

[@MarkvanVaals]

FYI to get accurate amplitude reading you need to set the lift angle for that specific movement. Note that not all manufacturers publish the lift angles for their movements. Also, just get a cheap demagnetizer. They cost less than 20 £/$/€ and within 10sec you can fix a magnetized watch.

[@djganton]

I was hoping someone would bring that up.

[@DarrenBates]

You can manually wind that Seiko 5, it has the relatively new 4R36. Any Seiko 5 with that new "superman" logo has it.

[@Pete...NoNotThatOne]

When measuring a watch’s stats on a Timegrapher, there are three things you need to remember. 1) Don’t do on an absolutely full wind. If you’ve been wearing it all day, let it wind down a bit for half an hour. 2) Lift angle. It can affect the results of the measure, and can vary between 42 degrees (Vostok movements) and 56.5 (old Seiko 5). Lift angels are usually available online, and worth setting. 3) Accuracy by itself doesn’t tell you much. Important stats are beat error and amplitude. It is possible to regulate even fifty or sixty year old movements in good condition to be +-10 seconds a day, but always let your watchmaker do the hard bit. And always remember; just because it says one thing on the Timegrapher, your accuracy may be vastly different wearing every day.

[@WilliamSunderland]

Glad somebody mentioned lift angle, the lift angle for a coaxial is in the 30s somewhere if I remember correctly. This can definitely change the readings

You indeed need to set the lift angle for an accurate amplitude reading. However, not all manufacturers publish the lift angle for their movements. The watchmaker should (and probably does) know this, he was likely only showing owners the rate and beat error to give a quick insight.

Even the lift angle was wrong for the most watches. With seiko you must wear the watch. 1 got 18 seikos the each runs ca 3 sek a day only the marine Master Run with 8 + but 5 jears always the same.

[@manot87]

Yes, what's up with that?

[@R023N]

He was probably thinking about the stated accuracy of the 4R movements. Seiko state their accuracy as -20 to +40 sec/day; however, that doesn't mean they can't be regulated to be more accurate; it's just means that Seiko aren't committed to regulating them to a very tight margin. They are mass producing these movements and don't want to deal with high number of warranty claims. That being said he's comparing apples to oranges here, he's dismissing the measured accuracy of the Seiko and instead comparing the stated accuracy of the Seiko to the measured accuracy of the Omega. As many have pointed out, it's just a sloppy video all around, and as much as I like Adrian's content, I think he needs to be called out for a low effort video.

[@kresimirpleic]

Adrian, two things: 1) lift angle, and 2) the 4R inside the Seiko can be hand wound.

[@SinnerAndSaint]

Correct. The lift angle is highly important for reading the correct amplitude. You can simply look it up via Google which will lead you to the well known calibre / movement websites that will display the correct lift angle for each movement.

[@JonathanCho-ni4bv]

Yeah, I was disappointed to see that Adrian does not seem to be aware of those two points. Also, measure the watch in different positions. Don't just measure in the dial up position because you may get misleading results. At the very least, measure by simulating the positions of a right-handed person wearing the watch on their left hand (crown down & crown left). Then you can take the average of all the readings.

I agree. Due to it being frictionless it needs virtually no oil. George Daniels said that if you get it serviced every 20 years it should keep good time for 400 years. I couldn't invest in a nice watch if it didn't have the coaxial 🤷‍♂️ so I guess I'm limited to modern Omegas.

The amplitude readings may not be correct, as it depends on the lift angle specific to the movement. Not all movements have lift angle of 52 degrees. For example, Omega 8800 caliber has the lift angle of 36 degrees.

[@nedflanders3769]

Especially on coaxial escapements though, the amplitude reading is always off. I think it needs a special kind of TG to get an accurate reading of the amplitude for this movement.

[@michaelriera6277]

The auto amplitude in some timegrapher is often off. Really need to manually set the lift angle for your specific movement.

[@jamescgarrett6356]

A really interesting insight, thank you for putting the time into this film. I have my own timegrapher and tried a similar experiment myself a couple of years ago. I immediately found that what the timegrapher displays in static conditions (regardless of position) varied massively from what I witnessed when wearing any particular watch over several days. For example, my Tudor Black Bay 36 (older version, ETA movement) showed around +/-3sec a day in various positions on the Timegrapher, but would be about -30sec off after wearing it for a week, while my trusty Seiko SKX would show massive variation on the Timegrapher (anything from +20sec a day to -30sec a day, depending on position) yet would be off my no more than 10sec when worn on the wrist. I’ve since migrated to wearing mainly CWC quartz watches, and Grand Seikos with 9F movements. Problem solved! Keep well :-)

[@JonathanCho-ni4bv]

Adrian, the amplitude reading of your Omega is horribly off because you did not set the lift angle. You kept it at the default of 52 degrees. But it should be set at 36 degrees for the Omega. Also, your Omega has a co-axial movement so your regular timegraph can't get an accurate amplitude reading even if the lift angle is set to 36 degrees. You need a different timegrapher for co-axial escapements to get a truly accurate reading.

[@neonteepee8453]

I think the 1900 has some separate circuitry for reading Co-Ax's and that's why he is seeing the sudden amplitude change, its recognizing it and changing the reading. I'm not saying it's accurate and of course you are right about the lift angle but mine does the same.

A timegrapher is a good way to get a suggested baseline for accuracy. What it "should" be performing at. However, using an app to keep track of the watch actually in use with all the movements, temperatures and whatever you normally put it through would be the best judge of actual accuracy. Makes for an interesting comparison between what timegrapher tells you in static position(s) and what actual practical usage on the wrist does.

As long as you’re not using the same watch everyday then you can really stretch out the service interval especially if the watch is relatively new (less than 15 years).

[@WatchmakerErik]

The watches start at a low amplitude and then kick up because the movement has to add momentum to the amplitude on each swing, so it takes a minute to get to full amplitude. For instance if you and a friend are on a swing set, it's very hard to just give someone one push and get them to 180°, where the ropes of the swing are parallel to the ground. But by giving a little push each time the person goes by you can easily get them there.

But when I talk or think about accuracy, a mechanical watch is never a part of the conversation. My Bulova Lunar Pilot, and even a $70 AliExpress Seiko homage watch I bought on a whim would decimate any of the mechanical watches on your table (or mine) when it comes to pure accuracy with their Seiko VK Quartz movements. And because they're quartz they require no winding and almost no service. Your Omega (and my red dial Aqua Terra) are gorgeous and something to aspire to own, but again, not based on their accuracy. And let's be honest, how many of us wear a mechanical watch enough week to week to keep the movement going anyway. So if you're likely to have to reset it when you do get around to wearing it, who cares how accurate it really is. Just my $.02.

4R36 do have manual winding. If you're shaking it around like that all the time, maybe that's why the beat error is horrendous? 😅 Anything beat error above 0.4ms needs attention.

And regular timegraphers are not able to correctly interpret coaxial calibre amplitudes.

Or shake it

[@michaelhayward107]

COSC and METAS are mere snapshots of a watches accuracy at the time of certification. 99.9% of watches use a lever escapement, so it's this, that causes the issue. The lever escapement requires oil to function because of sliding friction. These oils deteriorate over time, thus affecting long-term accuracy. This is why they have rate issues. The co-axial on the other hand, will keep its chronometer rating, because of the escapement design. This escapement uses a pushing action, so contact friction is significantly reduced. Therefore oiling is less of a concern.

My Black Bay 58 at -1spd, Rolex OP at +4spd, latest model Speedy at +2spd and the worst being my 2007 Seamaster running at -6spd. Not that I’ve checked them at all!😜

One thing to pay attention to when testing amplitude of watches, is the lift angle. The lift angle only changes the amplitude measurement and I believe on the Omega 8800 it is 36 degrees. A 346 degree amplitude is too high and to be expected when measuring with a 52 degree lift angle. I would try the seamaster again at a 36 and see what it says! Also some Timegrapher a have a special measuring mode for the coaxial escapement so I would also look to see if your has that! Cheers great video!

[@harrysmith3502]

Love a timegrapher. A good way to check the health of a second hand purchase.

[@eagz3394]

Great video and I love my mechanical watches but it certainly makes a case for Precisionist and other quartz movements.

[@andreaiacolina]

Nice video! Omega movements are absolutely great 💪🏻 I have an Aquaterra with the 8900 movement and its performances are like yours, simply perfect !

[@jlw48]

I recently received a new Rolex Datejust. I wore it for 61 days straight, day and night. It gained 18 seconds. So that's .295 seconds per day. I never had a watch this accurate and that test really takes into consideration differences in accuracy based on variable positions like case down, 3 down, 12 down, etc.

[@christianwolf3962]

Adrian, the Weishi 1900 is capable of handling coaxial movements like the Omega 8800. You need to set the lift angle correctly to have the correct amplitude (anything beyond 320° is too much). To adjust the lift angle press the red button once to stop the measurement then press 'menu/speaker' twice and adjust the value via the up/down keys. For the 8800 you want to set it at 36°. Press the red button again to restart the measurement. ;-)

[@ChasT-ns7pi]

A great and really informative video - my most accurate watch is a 2022 40mm Longines Legend Diver that is accurate to about 1-2 seconds/day. Even my two Rolexes and a Montblanc cannot match that. Cheers, Chas T

Nice video, as always. But, to the vintage Seamaster... you can't "overwind" a watch. It's impossible. The mainspring wraps around the arbor in the barrel and then it is that. When it is fully wound there just isn't anymore slack to tighten. "Overwound" watches are a term that means a movement which no longer runs and has a fully wound mainspring. This can be a broken balance staff, or a gummed up movement, etc. But it's not "overwound". Just wind your manual watches until they are fully wound and go on with your day. As long as you're not taking a vice grip to the crown you'll be fine.

[@michaelcozens7537]

Thanks for explaining the time grapher. Maybe a de magnetiser for £10 next before shelling out for a service.

[@paulbonaventura4969]

Explorer I works great after so long and that Omega is just amazing to see.

[@pragmatist7455]

I'm not at all surprised at the result. My Aqua Terra with the same movement has gone days with 0 seconds of deviation. Omega certified it for +1 seconds in 5 positions. Just amazing.

[@structurescience]

Watching from Sollentuna, vacation day 6/37. GLORIOUS FREEDOM!!!!

[@larryscott3982]

My Rolex OP Date, cal 1570, 19.8K bph, circa 1965, has been keeping -1, +2 sec per day for the last 10 yrs. However that’s by checking its time several times a week. Not beat error. On the grapher it indicates about +10.

[@sledgehammer2717]

@BarkandJack, The Weishi timegraphers glitch a bit at first with Omega Co-Axials, because it uses a different release system. Thats why you have this weird reading at first.

[@MichaelB-qx1eh]

Amplitude in the 230s is actually good and in spec for a Seiko. Minimum would be more like 190, targeting 220 for that movement. A lot of care can get it higher but the factory would ship it at 220.

[@timlo9667]

I have the Omega NTTD and Tudor BB58 GMT. My Omega averages + 0.5 sec/day. Last 3 days, I had 0 sec +/- While my Tudor averages + 2.8 sec a day over the last 3 weeks. Both within METAS specs, but Omega deviates a lot less. Being in the military, accurate time is important. I would zero my watch before a mission or major training exercise. Wish the Omega Ti NTTD is fixed lug, 8906 movement (jumping hour hand), Gladiator hands, and grippier bezel. Love the size, Illum., wearability, and thinness. This can be the future MilSub/Mil SMP. Just need to tweak it a little for combat use.

[@whosays2002]

Love this content Adrian!

[@BarkandJack]

Thanks mate. It was really interesting to make.

[@Mark-lj1dj]

Agreed. I enjoyed this one too.

[@CK24716]

For my Seamaster I can say, it runs differently depends on the site I’m laying down the watch over the night. If the dial is on the top, the watch runs about +1to2 Seconds, if I’m laying down the watch with the crown to the top, it runs around -2to3 seconds.

[@stevenwatchenthusiast]

Nice collection! Thanks for sharing collection! Not sure if I missed it but but wonder what the L.A. is on the timegrapher

[@BarkandJack]

Thanks mate. LA is lift angel, each movement has a slightly different lift angle, but the vast majority of modern watches are 52 degrees. And I couldn’t find lift angles for the vintage watches so I left it.

[@ph8077]

Oof! The way you just chucked that rootbeer down on that table made me gasp. 😁 My two Omega SMP's; one full Sedna & the other the black dial two-tone both run at between +1-2 sec/day. My Rolex YM 40 two-tone black dial runs at 0/day (over ~6 weeks, worn everyday when I first bought it) & my two-tone Tudor BB GMT "rootbeer" is running at -1. My two "dailies" - Bremont H1 Fury blue -2 per day & Tudor Coke +2 secs. My CW's: two original LE Bel Cantos & C60 Chrono...no idea!

[@rabtrekker]

This video was your best yet! While I am seriously, seriously happy with my Black Bay 54. One day I'll own an Omega, for the movement alone. Top tier watch making, that's AD accessible and without the status hype shenanigans. Grail worthy stuff. Keep the content coming Adrian 😊 P.S. BB54 accuracy = Worn -1 sec/day. Stored overnight face down +1 sec so can be nigh bang on.

[@ChritelleLinger]

Been watching your videos for a while now and was inspired to start a collection. Started with the MAMACOO, its specs for price and clean looks, now am looking for a dress watch to add.

[@mangabatwands]

I've recently began my obsession as a watch collector. And i must say- out of all the luxury brands I've been researching, for me the amzwatch's watches are the most intriguing.

[@tooslow8150]

If you own a lot of watches a time grapher is a must to keep an eye on watch health. Especially vintage.

[@Useruseruser32121]

I was waiting for the BB58, but thank you anyways for this interesting format !

[@josephstratti52]

The beat error for the 3135 is .8ms over 5 positions so it may not be much to worry over.The rate is set by micro Stella screws but I would test the watch in more positions to see if it gets better or worse.All these watches except the Rolex could easily be adjusted for accuracy.

[@louisthegame]

Love the omega and Seiko ❤. You should do this every year.

[@Cr41gAus7in]

Your Omega looks gold btw. Very nice 🤩

[@seanlukecorroon]

Hey Adrian, bingeing your content again as I loved the explorer 2 stuff you shot at the Matterhorn. Did you get your Exp2 fixed ? Hope all is well.

[@bassmannausaugsburg]

my 1994 Explorer 15270 runs -1 per day. Perfect watch for me.I have a GS quartz which gained 8 sec in the whole off 2023.

[@therascals8237]

Can you do a video on your Mark XX?? (with strap options)

[@mjhastings4534]

They are a beast and strap monster it's my perfect watch

[@lsimpson50]

Great video! I need a timegrapher. just for the fun of it.

[@martink8985]

Great video, I really enjoyed it! Do you also experience with your IWC Mark XX that you have to wind it fairly a lot to get it running? Sometimes I have to wind my Mark XX for around 20-30 times before it starts running.

[@elias8720]

Hey, i think the amplitude skipping at the Omega Sea Master is because of the Co Axial Movement. I had the same problem checking my Speedmaster.

[@strapped2time]

It’s been said, but you need to set the lift angle to get an accurate amplitude. The Omega coaxial has a vastly different lift angle (38) than the rest which are mostly closer to that 52.
