San Martin SN-030 Type-B

I got this very nice Type-B on sale for a good price. It has a YN55 movement which I had to look up. I found it's an Orient so I got the watch. The first couple weeks it lost about 6-8 seconds/day so I thought I could do better. I adjusted it and wore it and it was too fast then too slow but for the last 8 days I have worn it except when I shower. It is now 1 second slow. I think that'll do. I can't speak to the longevity but I'll vouch for the accuracy
