How to measure curved spring bars?

Post by sierra11b » Thu Feb 15, 2024 5:57 pm

Entertaining the idea of servicing this one sometime this year:

viewtopic.php?t=77675

According to my crap calipers, lug with is 18mm on the watch head, but the original roached curved spring bars are 21mm tip-to-tip when fully extended.

If I purchase 18mm curved bars are they 21mm? Never had the opportunity to order curved bars.

I always order the same size. So it 20mm I order 20mm curved spring bars and never had an issue.

I usually just get from Amazon or eBay.

I bought a cheap watch from a crazy man
Floating down canal
It doesn't use numbers or moving hands
It always just says now
Now you may be thinking that I was had
But this watch is never wrong

Typically you measure from the spring bar flange (shoulder) flange for the length. I usually recommend a 19mm spring bar for a 18mm lug watch. That way you have full engagement into the lugs and the flanges rest against the case.
