Android Exotic Divemaster Ceramic AD481 (Add your watch to the comments below…)

The Seagull caliber TY2807 is an affordable skeleton dial automatic watch movement. This is essentially the skeletonized version of the Seagull ST16. this caliber is available in a silver or gold tone finish.

Stuttering Seconds Hand:

Similar to the Miyota 8 series movements, the Seagull TY2807 seconds hand is an indirect drive system, therefore, you may experience “stuttering” seconds. This is normal and you can read more about it here.

Replacement Prices:

At the time of this post, replacement prices for the Seagull TY2807 were found online for around $35.00 USD.

Watches with this movement:

The TY2807 pictured below was found in this Android (Aragon) Exotic skeleton dial dive watch. If you have a watch with this movement, please share it in the comments.

21 or 20 Jewels?

Android watches using this caliber have been found with casebacks claiming 20 jewels and 21 jewels. It appears that the 21 jewels version is more accurate and perhaps Android made a mistake with the “20 jewels” casebacks. It doesn’t help that, as with most made in China movements, pertinent information such as caliber number, jewel count, and origin is not clearly visible on the movement. Therefore, we can only go by crowd-sourced data based on real world watches – in this case, there are two known examples: AD481 which Android (Aragon) says has 20 jewels (pictured above) and AD562 with 21 jewels. See comments below for more info.

Hey there! Based on what I’ve observed it appears that the gold tinted TY2807 movements in Android watches are labeled as having 20 jewels and silver tinted versions are labeled as 21. I’ll follow up if I get a chance to compare each version in person at some point in the future.

I have this movement in a old Armitron watch but would like to put the movement in a different case preferably a copper one but having trouble searching for one. I have searched for ty2807 and ST1601K2 and not many cases pop up. Can anyone help me with my search for a compatible case?

I have one in my Kenneth Cole, The watch is about 14 years old now and it still hold decent timing. Of all my watches this one gets the most attention from 3rd parties

Just got an Elgin FG8030 with this movement in it. Unfortunately the paperwork that comes with the watch offered almost no information on the movement itself so thank you for this.
