This would be the Louis-Bolle Pioneer?Is "Manual wind TY - 3100 movement w / 18 jewels" made by Seagull?
Interesting. This is the linear open-heart that was turning up on several internet brands a couple of years ago. Invicta had one in their Objet d'Art series, too. My impression is that watches with this calibre usually seemed to have been assembled by Million Smart Enterprises, who I think (not 100% sure) souce their movements primarily from the Liaoning Watch Factory. The design of the back of the balance sub-assembly seems more in keeping with Million Smart's other, more famous/notorious open-heart (remember Montres Allison?), rather than Sea-Gull's equivalent ST25.
I have never seen this calibre listed on the Sea-Gull on-line catalogue, or on Tsinyi's, so it is surprising to see it designated with the Tsinyi 'TY-' code. AFAIK Tsinyi only deal with Sea-Gull, so all I can say is: :-S
Whatever its origins, this is a significant Chinese calibre as it is the first 'linear' layout movement from this part of the world. As for its reliability or accuracy, I would suggest making inquiries on the Afforable Watches forum and PMWF, where you will probably find some owners.
