This strap will fit IWC, Omega, Brietling to name a few and enhance their quality as great sports watches. The band is made of comfortable to wear natural rubber that can be worn with either the smooth or patterned side out, it has a heavy duty brushed stainless steel butterfly clasp. This same quality band with a brand name on the clasp would be selling for $200-$300, it's priced at a very reasonable $45 with shipping included to any destination in the USA. Member NAWCC.
