[@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.

[@ggn1]

Which manufacturers publish lift angles?

[@MarkvanVaals]

@@ggn1 When (widely) known, they can be found on websites with calibre information. I assume this information comes from maintenance documentation. It seems for instance all ETA and Sellita movements are known but some manufacturers of in-house calibres are more secretive.

[@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

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.

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.

[@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.

[@Kranberry777]

Please correct me if I'm wrong, but the Co-Axial movement seems like the cheapest way to get a well-made, decently good looking, interestingly-engineered, and reliable mechanical movement

[@Mark-lj1dj]

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.

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 :-)

[@drnick40]

My Omega Aqua Terra does the same thing. It is the most accurate watch in my collection. Bulletproof!

[@George-jg9sy]

You must change the lift angle for each caliber to the specified degrees by the manufacturer for an accurate amplitude reading.

[@DarshanParajuli]

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.

[@khronokraze]

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.

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.

Lift angle. If you set it wrong because you don't know the correct one it won't affect the rate but it will affect the amplitude which can be misleading because you could think a watch that shows 230 may already qualify for service but in reality due to incorrect setting it can work at a healthy 270. It would be nice to mention that Seiko designs its watches to operate at a lower amplitude. That Seiko new/out of the box is 260-270. Beat error 1.0 ms or lower doesn't affect the rate. All rolexes are still good (unless you feel resistance while winding, then it's time), IWC and Seiko too. Your grandfather's Omega definitely needs servicing. Do it quickly because such a watch deserves to be worn. Old lubricants combined with the dirt that has accumulated over the years create an abrasive paste that wonderfully destroys the mechanism that has been lying around for so long. I can't wait to see the Rolex result after it comes back from service.

[@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.

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.

[@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. ;-)

[@michaelcozens7537]

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

[@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.

[@TyreAlmasri]

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.

[@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.

[@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.

Omega rocks! I own a speedmaster first omega in space. Highly accurate within cosc

[@Cga1225]

Go Omega! I have tried testing my Aqua terra (2023 small seconds) vs my Explorer 40 (2024) on accuracy by setting both Hour/Minute hands and second hand on the exact same time. After 1 week of using them, they kept the same time. I was planning to try more than 30days of testing to really see the results, but thanks to your video and the timegrapher machine, did it in a few minutes. Surprised with the Seiko sports because mine runs late, but even more surprised with the Sub results of +13secs!! Omega Metas certificate is no joke, results are 0/+5sec/day. you would never be late!

[@harrysmith3502]

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

[@GRAFHC]

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.

[@Vox-Populi]

I have two 1999 Omega watches and they're both +3 secs day. Love them!

[@andreaiacolina]

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

[@BigFerg-hf6uv]

Omega 8800 family of movements are rockstars no surprises at all. My Raily has an 8806 easily the best modern day movement in a modern watch I can think of.

[@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.

[@MikeOBrien1945]

I have my dad’s Omega that is exactly like your grandfather’s DeVille…even on the same type strap. I had my local Omega/Rolex guy service it a couple of years ago. I wear it every couple of weeks. Keeps great time.

[@structurescience]

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

[@kiwilonewolf]

I wonder if the co-axial movement has something to do with the weird amplitude measurement for the Omega?

[@tooslow8150]

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

[@rainerbuechse6923]

On the Seiko: „Zero seconds a day is quite remarkable“. 😂

[@nautica1504]

I was like uhhhhh what Sieko 5 did you get?

[@Koishishibaman]

I have a bunch of 4r35 Seiko that run close to that. 20+ orange samurai that always runs plus 3 a day. My 6r movements.....all over the place

[@bigbodykarate6403]

No its not weirdo , they are literally the easiest brand to regulate . i literally have 8 seikos running within cosc and another 2 at +5 for sub 1000 dollar watches thats fkn insane .

[@josephstratti52]

Zero seconds a day that 4R36 is as @rainerbuechse6923 says quite remarkable as seiko produces a lot of these movements and you can be lucky and unlucky it’s a seiko Lottery.

[@ernstplomann5003]

why do you think that they are easier to regulate?​@@bigbodykarate6403

[@andyburton9201]

I have to say I am a bit of a nerd when it comes to watch accuracy, which you really shouldn’t be with mechanical watches! Though I don’t use a Timegrapher I set it in the morning, wear as usual for a day and check 24hrs later against my reference time (phone). This gives you a much more realistic reading. My most accurate being my Tudor Ranger with the latest movement that seriously sits at +/-0.5 spd. 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!😜

[@xiaodongwang2849]

Thanks

[@louisthegame]

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

[@imranchowdhury4972]

Nice presentation as well for the details on timegrapher machine.

[@ajmarion]

Also just pointing out that the room needs to be as quiet as possible when using the timegrapher, it has a very sensitive microphone. If you’re speaking right next to it, it will pick up that noise and and affect the data readings

[@blacktipmedia2519]

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!

[@ehabal-hanash2533]

Seiko seems very accurate right??

[@jimmason8502]

Zero seconds per day is well, pretty accurate.

[@duncancurry]

You can track the Co-axial movement back to 1980 when George Daniel’s patented it.. of all the brands he too it too.. Omega chose to use it and worked with him to integrate it into the watches… that’s why the movement is so kick ass… it goes way back to one of the finest horologists and watch makers of the current era.. and only Roger Smith has been honoured to fallow in his footsteps.. awesome video Mr Barker.. Always wanted to know how these flipping machines actually worked 😎

[@michaelriera6277]

So you honestly didn’t know how these “flipping “ machines worked?

[@Useruseruser32121]

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

[@UwaseTae]

It always amazes me how much beauty and precision are added to the parts of MaMaCoo 's watch 99% of people will never see.

[@BfoSHIZnats]

I regulated my San Martin with the Seiko NH34 GMT movement and got it around COSC spec. Did various positions and now when wearing it at work and moving around it comes out to essentially 0 seconds per day. I never have to adjust it if I keep wearing it.

[@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.

[@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.
