I have a watch head (vintage watch...doesn't have any branding), no spring bars (don't have the ones previously on the watch).
I do have a basic leather strap (19mm) which fits snugly.
I don't have a digital caliper (yet, I guess!)
Now I need to figure out what kind of spring bars to get (I will probably order other straps for fun too).
I thought this would be easy to figure out, but then I found these pages:
Watch Band Spring Bars | Double Flanged Spring Bars | Esslinger.com
Spring Bars - All Types
and now I am completely confused!
1. If a strap size is 19, should the spring bar length always be 19?
2. Do I get a double shoulder? Double flange? (are double shoulders and double flanges just to make it easier to grab? Are those basically the same?) Special ends? Single Shoulder?
3. Is there a way to know what thickness spring bar I need? Is there a "standard" for most leather straps online (like if I go get one from HODINKEE or JPM)? Is it generally 1.8mm with most leather straps ordered online?
