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.
Longines · Conquest
Ref. L36604566
The Longines Conquest Chronograph Quartz takes a 21 mm strap: measure between the lugs and that is the only number you need. We list 6 straps in that width. Built for water, it wears naturally on rubber or a nylon NATO; a leather strap keeps it for dry days. With a 41 mm case and 300 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.
