Strap for Conquest Quartz 34 Stainless Steel / MOP

The lug width of the Longines Conquest L3.377.4.87.6 is 17 millimetres. This measurement is specific to this model and is non-negotiable: a strap of different width will not fit correctly into the spring bar holes on the case. To verify compatibility, measure the distance between the two lateral spring bar holes using a millimetre calliper, positioning the tool perpendicular to the case.

For a 34-millimetre Conquest, alligator leather represents the most sophisticated aesthetic choice: its natural grain texture dialogues perfectly with the brushed stainless steel case finish. If you prefer a modern and sustainable solution, vegetable-tanned calf offers elegant texture and warm colourways that age beautifully. For sporty contexts, silicone rubber or Cordura NATO straps guarantee maintenance-free operation and quick changes.

Strap replacement requires a spring bar tool. Position the watch on a soft surface. Insert the tool tip into the groove on the back of one spring bar, applying slight pressure to release the internal spring mechanism. Remove the bar from the case, withdraw the old strap and thread the new strap onto the same bar. Reinsert the bar into the case lugs until it clicks into position.

The 17mm strap is compatible exclusively with watches that have the same lug width. It is not suitable for models with different measurements (16mm, 18mm, 20mm). Before purchasing an aftermarket strap, always verify your watch's lug width by measuring the distance between the spring bars. At milanostraps.it you will find a dedicated collection of 17mm straps compatible with your model.

The lifespan of a leather strap depends on materials and usage patterns. A quality alligator strap can last 8-15 years with regular maintenance (cleaning with a damp cloth, conditioning every six months). Shell cordovan is more resistant to wear but requires protection from humidity. Vegetable-tanned calf offers a service life of 5-10 years. Silicone rubber or Cordura NATO straps have a lifespan of 3-5 years under daily intensive use. Atelier Casati Milano provides an 18-month warranty on bespoke straps.
