Android AD576, Hager Commando (Please add your watch in the comments below…)

This Sea-Gull caliber TY2806 was found in an Android Divemaster Espionage watch. This movement is reportedly the same as the Tianjin caliber ST1612. Tianjin and Seagull are the same company (Tianjin Seagull Watch Group), but they have offices in Tianjin, China as well as Hong Kong. Apparently the different caliber numbers correspond with where the movements ship out of.

You’ll notice no engravings or inscriptions on the movement or rotor. Not even a jewel count.

Hager Milisub/Commando Usage:

This movement was also used in some of the Hager Commando models (as of a post on their site in 2/2012) although they appear to have switched to the Miyota caliber 9015.

According to Hager:

The TY2806 automatic movement has a similar train layout to the Japanese Miyota 8215 movement, and the winding mechanism has a Seiko-style auto-winding ‘Magic Lever’ system inspired by Seiko. This provided Sea-Gull with a modern, simple and efficient full-sized wristwatch calibre that served as the basis of a myriad of complicated variants. The TY2806 movement is produced by Tijin Seagull in China. It is a cost-effective high quality design that is used by a lot of watch brands such as Android, Rotary, Ingersoll, Fossil, and Zodiac watches etc., One Swiss company uses the ST-16 ebauche in their watches but they brand it the CL888 and it is labeled Swiss Made.

Furthermore…

As mentioned above the TY2806 has a similar train layout to the Japanese Miyota, and the winding mechanism has a Seiko-style ‘Magic Lever’ system that winds in both directions, which means the TY2806 takes less wrist movement to wind the mainspring. Even if you wear your watch on a daily basis we recommend that you wind it once every two weeks to keep the wheels in motion and oil fluid.

As for accuracy, Hager goes on to say:

In terms of specs, the accuracy rate is about +/- 10 to 35 seconds per day unadjusted for this particular movement. Our watches have been timed out to approximately +/- 3 to 20 seconds per day unadjusted in testing. Some of our customers who have been wearing their watches regularly have reported that they are seeing +/- 3 to 7 seconds a day (testing with an atomic clock), which is truly incredible as one would only see this kind of accuracy on the higher end models that meet the COSC standards (btw they only promote Swiss chronometers made by Swiss manufacturers now).

Side note: The Android model does not have a date, but the Hager model does.

Replacement Prices:

At the time of this post, replacement prices for individual ST-1612 movements were found online (directly from Sea-Gell) for $35.49 USD, and as low as $18.17 from other China-based sellers.

I love Watches, I buy watches that fit my budget and once in awhile a Rolex or Breitling. Long time ago, 20 years maybe, I bought this Tag, a fake Tag for about $100 dollars, it happens that this watch came with one of those Seagull movements, thanks to your database I finally know. But I need to say this: This Fake Tag, keep the time a lot better than my Breitling and even my Rolex, I don’t know how, but when I wear this watch and I set te time with my phone it never lose a minute for… Read more »

History goes, back in the 50’s Seagull bought machinery from a swiss watch company and ever since they’ve been making automatic movements succesfully. It’s cheap because they don’t take the time to polish each part to the same extent do the swiss manufacturers.

I can’t speak for long-term quality, but I have seen and taken apart this movement in several manufacturers’ variations. The build and finishing are not as nice as the Miyota 82xx, but they have been as accurate, offer hacking, seem properly lubricated, and have a quiet autowind rotor in contrast to the noisier Miyota. They are also half the price and use the same hand sizes and dial feet positions. Some may have date wheels that are at a different diameter for the dial windows, but I have only seen 1 like that out of the 5 example.

There is a chart of equivalent, probably from on here, of Swiss/Japanese/Chinese 26mm movements which indicates that the Chinese movements all have a common, but different, dial feet
positions by a couple (significant) of minutes from the Miyota.
Strangely all the ETA2824 clones have theirs the same as the ETA.
It’s on Watchuseek.com by Torsten under ‘comparison of movement specs for watch projects’.

Thanks for your reply. I will check that out. I haven’t encountered what are sold as “DG 2813” movements having dial feet positions different from the Miyota 82xx series, specifically 82xx with date window. The dials I have seen for sale online tend to have two pairs of feet, such as ETA and Miyota 82xx/DG2813, so that you remove one pair of feet. I’m seeing many more of the Chinese build-your-own parts center around the 12? ligne Seiko first and second-tier movements. I believe I recently worked with a dial for a traditional aviator that had feet for the Seiko… Read more »

I have a Loreo Submariner homage with this ST15 movement that Is currently running at +/- 0.5 seconds per day (based on a timing run of 6 days). Time will tell how long it maintains this level of accuracy but impressive nevertheless.

It’s currently running at +2 to + 3 seconds a day (checked with WatchTracker) which isn’t bad for GBP 50. When I first received it was running at +20 secs/day so I adjusted it and got lucky with +0.5, and I haven’t made any further adjustments since. Hope your Loreo continues to give you good service.

Its inside the watch, it’s looks don’t matter, how it keeps time does. If I have a choice of an expensive watch that doesn’t keep time and an inexpensive one that does the inexpensive one is worth the money, the expensive one is worthless.

Claro Semag was a ‘fake-abiding’ business in watch calibre.
No one’ll mourn their being off the world-market via Switzerland and e.g. the UKIPO.

Sorry, but it’s unwittingly true, my dear watch-folks …
It’s the ‘swiss-made’ ghost that has got them off-stage …

I love my Alpha 1993 Planet Ocean with the TY2806 caliber inside.
Tworx without any problems and stays between -2 sec./+4 sec. per 24 hours/day. Much easier to handle @setting the watch right than e.g. the ETA2824-2 or the Sellita SW200, let alone the Rondamatic R-150.

Today my last – but not least – addition in my latest review of my watch with the ST1612 inside: when the calibre changes between respective dates, it does this spotless with áll 3 hands on the 12 indice.

I have never ever seen this accuracy in dates-changing before!!

I find the ST1612 a really refreshingly accurate movement; I do like them even better than the similar ETA–, Sellita SW200– or even the ‘fake’ CL888– or the Ronda R-150 calibers.

This movement is also used in the DeLorean Orbit (with day function…). Its proven +/- 8secs a day for me. Tested every 2 days (like all my watches) and that is for over 3 months now. As an aside, this accuracy (and the watch has many more complications.. Day, date, month 24 hr in form of a night/day wheel, familiar to all)… So it beats out a (1970s) Submariner (serviced regularly but never does better than 9 to 12 secs +/- a day, and a new Omega speedmaster… Well, 2016 I believe this model was unveiled at Basel.

Hello Sir, I’m looking for hands that are fitting for the movement ty2809 but can’t find any. Do the hands of a miyota 8215 fit on this movement? Ore other hands that fit that are easy to find.

I have a few watches with the ST1612.
The movement can be adjusted to a very good rating, seem very stout & well made.
The only thing I am having an issue with is the sweep seconds hand doesn’t track very smoothly, kinda jerks & flops around. Polished the pivots. It cleaned it up a bit.
Maybe needs a slight tension spring to keep the matting of wheel & pinion, not sure. Need more investigating into the problem.

YO! Eto all.
I found that my particular problem with the ST1612 apears to be solved by adding a little tension to the friction spring under the rotor axel. Tweaked it & smoothed the sweep seconds hand to be very acceptable.

I have this movement in a kit (man crates.com/projects) watch given to me. Pretty poor instructions with it, but has 2 faces (white/blue) and a selection of hands. My problem is that the hands don’t move when turning the crown in any position. The date will change at the furthest out detent, and it will wind and run, and the self winding mechanism appears to work. Is there something else I need to do?
