This Longines is not mine but I bought it for my eldest son when he passed his professional exams about ten years ago. I'm looking after three of his watches while he has work done on his house.
That strap would be perfect for my only trench watch, where can I get one ?
There was a chap in the US that made them, but he doesn't seem to be around these days. Similar come up on eBay This chap makes real beauties, including original style buckles in silver.
