This Seagull caliber TY2806 was found in an Android Divemaster Espionage watch. This movement is reportedly the same as the Tianjin caliber ST16. 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.

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… Read more »

Any way to find out Real details as to quality of Balance Wheel(Material), hairspring(Material) we seem to be in the dark and I assume Glucydur, Nivarox, Anachron etc are terms Uknown in China.
The rest is just waist of time…

What do you want for $20 to $40 that is replaceable instead of spending 2x or 3x that to service it?

Mine is Rebosus RS022-MV07 and surely has this caliber which from my experience is match better than the 9015 and comparable to the 40N5A

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… 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.

Same experience on my Loreo. Amazing accuracy.

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.
