Omega Speedy tropic strap reccos UK

There are tropic-style straps, then there are Tropic(TM) straps:

I’ve tried both and I’ve never found a tropic-style strap that was as comfortable, soft, or flexible as the “official” Tropic straps. (“Official” because it’s a company that bought the trademark and not the original one from the 60s, but still quality).

Unfortunately, the “official” Tropic is not available in 18mm. But if you want one in 20mm or 22mm, they are available from UK-based sellers WatchGecko and WatchObsessionUK.
