Guaranteed comfort and convenience by MONSTRAPS.

Our latest generation of tropic strap, now molded in FKM rubber for superior durability. This is the same top grade rubber used in aerospace industry. As usual, our straps are resistant to UV rays, extreme temperatures, mechanical stresses, chemicals, and seawater. All our FKM tropic strap also comes with pre-installed quick release spring bars for easy strap change. 

This is not the typical vintage style rubber strap which is molded from cheap silicone or TPU rubber. Our tropic strap requires no breaking in and is soft and pliable from day one (there is no need for weeks or months of wear to break them in or even soaking them in hot water and compromising on the lifespan of your strap)

Please note that this is a straight end strap and should fit universally on most watches with the correct lug width.
