I've had my 2531 16 years and haven't worn it much recently (needs an extra link in the bracelet). I popped off the bracelet for the first time this morning and tried it on a few NATOs but didn't like it on any of them. My blue Isofrane is 22mm, so that wouldn't work. I then tried it on a Tropic (I blame Ed) and really like it.

Do you have a SMP 2531 or 2254 on anything other than the standard bracelet and can you upload pics please?
