FKM weirdness and the San Martin SN007-G-X

I barely managed to wake up today, courtesy of a hectic day, stress, and staying awake too late to decompress watching a video about convergent evolution - a subject I may one day investigate for its horology connection, but that's for another day.

The San Martin that I'm wearing today isn't weird at all and is actually one of the better watch in my collection. However, it's fitted with an FKM waffle strap and while it's a very good match for a vintage looking 62MAS re-creation it feels...well, it doesn't feel weird but FKM sure doesn't feel like rubber or even silicone. It's not an unpleasant feeling, just a bit strange.

FKM doesn't look any different from standard rubber, except that it's softer. It's a bit less supple when compared to silicone rubber but not to any significant degree. It's soft, it's resistant to chemicals and heat, and it doesn't attract dust and lint like silicone does. But every FKM strap that I own gave me the same slightly weird feeling when I touched them. 

I used to be a bit apprehensive when I first wore FKM straps, fearing that this oddity would translate into skin allergies, but the truth is that for me FKM rubber straps are better than rubber or silicone in the heat and humidity of our summers.

So I'm curious, am I the only one who noticed a different feel to FKM rubber, and what's your opinion on FKM straps?

I think this is a safe place to start with a confession: until recently I was completely ignorant that FKM is the material. Before I though that FKM was a manufacturer and that it became a synonyme for all rubber straps. That misconception was fed by all the cheap silicone or rubber straps I once bought that had "FKM style" in the name.

So for many many years I was unaware that a material called FKM existed and I have no experience with them. But I think your post is a reminder that I should get a real FKM strap instead of all the "FKM style" ones to find out how it's different. Thank you for that!

I don't think I ever saw a strap advertised as being FKM style. That might be the first time that a material instead of a design is homaged.
