The fit can be a little tougher than OEM and sizing can be a little nerve wracking (protip: read the ENTIRE page before attempting since wrists are NOT symmetrical). The black rubber is subtle and can be worn during the day and evening and is a treat in these warmer/humid months.
As advertised, the FKM rubber is soft yet not sticky, strong yet pliable, and looks really good. The clasp mechanism is solid, I just wish its buckle were a little more solid, without having a bigger footprint. Overall, I'd recommend this strap, and would purchase it with normal springbars in the future.
Love it. Great addition to my Cartier Santos Medium
Unfortunately the strap doesn't snap into place for me so they're useless. Waste of money.
There are many gaps between the quick change part and body.
Not a firm fit.
The part of the interlock is considerably thinner than genuine.
The quick change part protrudes and create a step.
With a slight force, the interlock comes off and the belt can be removed easily.
In short word, not safe.
