Mine is 20mm wide. And while visually on the strap the curve does not look extreme at all, it is really how close the pin holes on the watch lug are to the case that determine if straight pin could work...

in my case even the straight pin alone (without a strap does not fit)

1921 with straight spring bar?

 
 By: Ping.Timeout : June 21st, 2022-09:29
Hey folks. Finally i have found straps i wanted to purchase, however they come only in straight spring bar. I understand that the 1921 uses slightly curved bar. Any idea if strap with straight bar would fit? I have the 36.5mm version. ...  

Order some curved spring bars …

personally would only fit the original specification spring bars. They were specified for a reason.

Have you been successful inserting a curved pin into a straight pin designed strap?

On my side I was not able to so ending up ordering strap just for my VC…

Yes…

 
 By: Cpt Scarlet : June 21st, 2022-11:08
But it depends on the thickness and texture of the strap.

good to know. I have not been able to so far!

Good tips. Thanks.

While I don’t have your reference, my traditionnelle VC also has curved pins and can only work with curved pins

 
 By: Chronometer (aka yacomino) : June 21st, 2022-10:14
I tried fitting some of my straight pins strap on it and it won’t work because the pins are too close to the case. I suspect it is the same for yours. Have your strap custom made by a strap artisans which can make them to accept curved pins

That is likely the best course of action indeed!

You need to give us some tips and tricks

 
 By: TeutonicCarFan : June 21st, 2022-11:27
In strap changes while minimally scratching the lugs!

I believe the experts here can help

 
 By: Ping.Timeout : June 21st, 2022-11:34
Me = newbie

Well, I am no expert either but I do change them quite a bit! I won't say I never scratch a watch but here are a few tips that helped me...

 
 By: Chronometer (aka yacomino) : June 21st, 2022-12:12
Since I order all my strap customer made, I always order them with quick release pins which require no tool to change - easy enough! When I do have a watch with a standard strap on it which I need to remove, I use the black strap tool (see picture). Now t...  

Are the holes in the lugs also angled with the trajectory of the curved pin?

 
 By: toxly347 : June 21st, 2022-12:33
I have been tempted to get curved pins and a curved thick strap for a Geophysic, which has a gap between the case and the strap even at the centre of the case, but so far remained cautious.

I think it depends on the watch...

 
 By: Chronometer (aka yacomino) : June 21st, 2022-12:40

Thanks

 
 By: toxly347 : June 21st, 2022-13:44
I think it is best to continue to use as intended by the manufacturer.

yeah I would agree here

 
 By: Chronometer (aka yacomino) : June 21st, 2022-14:47

Yep

 
 By: Ping.Timeout : June 21st, 2022-15:15

This is true

 
 By: Ping.Timeout : June 21st, 2022-13:46
I was curious to i checked the VC and JLC holes, they are similar in terms of angle. Others may be different.

Many thanks

I have the other tools, not the black one. What is the name of it? It seems very helpful. I hate the metal Bergeron on my iwc or vc where the strap is very thick/ low compliance. I also have horotech screwdriver makes link removal easy! I also don't get w... 

You can find the black one in several places as it seems to be a tool that rebranded...for example...

 
 By: Chronometer (aka yacomino) : June 21st, 2022-20:21
Hodinkee has this tool branded as their own, and other various straps maker online.

What is the material of that one?

 
 By: TeutonicCarFan : June 21st, 2022-20:26

I have the 40mm with curved straps/quick release, so I ordered curved, custom-made strap

 
 By: Moka-Tiger (Ron) : June 21st, 2022-14:04
Etsy is a website where craftspeople all over the world make and sell custom-made straps, etc. Before I ordered, I asked the seller if he could make curved straps, like the OEM strap in the pic that i sent him. He said yes. I ordered the strap on June 1, ...
