Recently got my first aftermarket strap for my 372 and it was from the very well-known strap maker Peter Gunny.
This is a Caitlin 2 and it came exactly as I imagined. I love the distressed looks of the strap and how soft and comfortable it is on the wrist. I am really pleased with it.
It goes without saying that the new strap completely changed the character of the watch. Previously I was using the reddish OEM strap and that gave the watch a more formal look and feel. The Caitlin 2 gives it more casual and rugged look.
If you need a good strap, you know who to find.
