as far as i know this is seiko's only Double rotating bezel diver of the early 1970s era. as you could imagine not many were sold and even fewer survived the last 50 years in good condition.
with main issue being the inner rotating chapter ring paint would flake off during servicing as the paint was not coated with a clear coat to help preserve the paint from flaking off. unfortunately my lume indicator in the inner rotating chapter came off sometime during its life but luckily the rest of the color markers are still there.
The watch originally came on a railroad bracelet which I have not been able to find a replacement but this AM bracelet seems to work with it.
how it the regatta timing aspect works:
you would hear a pre starting gun and that would indicate you've got 10 or 20 minutes before the starting gun to start the race so you have 10 to 20 minutes to get yourself in position before the actual starting gun fires. you would turn the rotating bezel to the minute hand e.g.
20 min race=zero min marker to the minute hand
10 min race=10 min marker to the minute hand
so you would know much much longer you've
got to get your boat in position before the
starting gun fires.
bang goes the starting gun goes off and off you go, and once you cross the finish line you would rotate the inner chapter ring indicator marker to the minute hand and you could time your race of how long it took you.
• sharp case lines
• double rotating bezels
• simple 6119 movement
• unique color combinations
• little on the small side for me
• would of liked a clicking bezel
