G10 is the movement in the moonswatch . its a sealed unit . cant serviced. price is about 60usds. so once the movement is toasted. repair cost become highter than watch price. so it will easily become a land fill.
It cant compare with lemania entry level movement neda. it is like comparing benz A class to a maruti.
seiko VD series is great movement.
But im talking about automatic chronographs and its economies to scale.
i have seen many ads on ebay with used below 2000usd chronograph watches with issues. some have jammed date mechanism , some has chronograph hands are not resetting correctly. they are selling mainly because it is not worth to fix. even a servicing a mechanical chronograph is about 3-4 times higher than a regular mechanical . So if the watch is cheap, costs will easily overrun the watch value.
yes. Lemania is better than Valjoux . Even the real moonwatch ia also a lemanian calibre. Valjoux 7 series has common user complains too. like roter wobble issues.
Seagull ST19 does not have a russian connection or not Valjoux . its a Venus Calibre 175 column wheel chronograph movement in 1950s. Venus has sold the technology and machinery to a chinese PLA to fund their new movement development.

Yes its chinese and only 200usd. we cant expect QC on that price range. what cant be go wrong. literary everything. but it has really good reviews on internet.
