Yes I had one on a tropic strap. After the initial excitement I didn’t really bond with it, partly because the strap tapered to 16mm and on me it didn’t look right. I quickly noticed the time keeping and power reserve was well off spec, so I sent it back for a refund, at my expense under the t&cs. With the cost of that and the difference in exchange rate when the refund came through the whole experience cost me £80. Lessons learned.
