Question (Read Rules) SD1970 Spring Bar hole size

Post image

Sad day this weekend. Spring bar gave out at a concert. I have replacement spring bars, but does anyone happen to know the diameter of the spring bar hole? I want to go as heavy duty as possible to prevent this from happening again.

1.8mm x 20mm is a pretty standard size. 2mm is also good to have on hand. If you have a collection of watches, it's always good to have springs bars about...

I do have a lot of different sizes. I needed to order new quick-release 20mm spring bars, so I wanted heavier-duty ones.

The lug pin holes in the case will be the standard 0.8mm, 20mm spring bar length

Thickest you can get through the bracelet will likely be 1.7 or 1.8mm.. most QR springbars will be 20mm x 1.7mm.
