[REFERENCE] ASIAN movement drawings and datasheets

[Emilio]

Here, we will add the most common Asian movements' official blueprints to have the references at hand.


NOTE: on many occasions, ST (Seagull) movement references are equal to YT (Tianjin Seagull) movement references but sometimes aren't. You can check that on the title of each file.



ST36 - 6497/6498 "equivalent"

ST3600 - ETA 6497.pdf

ST3621 - ETA 6498.pdf

ST19 chrono - Venus Calibre 175 chrono "equivalent"

ST1901.pdf

ST1902.pdf

ST1903.pdf

ST25 - Angelus SF240 similar offset of sub seconds BUT NOT THE SAME - BEWARE

The difference is around 0.8mm

ST2555 - SIMILAR SF240 OFFSET BUT NOT EQUAL - YT2555.pdf

ST18 = TY2661 (auto, 1812/ETA 2892) (incorrectly referred to as ST26)

ST1812 - ETA 2892 - TY2661.pdf

ST21 = TY2130 (auto, 2130/ETA 2824) (incorrectly referred to as ST24)

ST2100 - ETA 2824 - TY2100.pdf

ST2130 - ETA 2824 - TY2130.pdf

I always wanted to ask this question: Is the 6497 second wheel interchangeable with ST36?
