Omega Speedmaster watch strap guide
One black dial, four different directions. Explore suede, nylon, rubber and woven straps, starting with the 20 mm lugs of a specific Moonwatch reference.
IWC Schaffhausen · Portofino
Ref. IW372406
The IWC Schaffhausen Portofino Chronograph MecaQuartz Stainless Steel / Black / Bracelet takes a 20 mm strap: measure between the lugs and that is the only number you need. We list 37 straps in that width. A chronograph carries a bit of sport: perforated leather, rubber or a sailcloth strap all sit well. With a 38 mm case and 30 m of water resistance, a strap of medium thickness keeps the balance. Most straps here come with quick-release spring bars, so the swap takes a minute and no tool.
Width is a starting point. Check the case and end fittings before choosing.
