Strap for HydroConquest 41 Automatic PVD / Grey / Bracelet / USA

The lug width of the Longines HydroConquest L3.742.2.76.6 is 20 mm, measured between the two pins that secure the strap to the case lugs. To verify this specification precisely, you can contact us with the reference number L3.742.2.76.6 and we will provide detailed technical documentation.

For the Longines HydroConquest L3.742.2.76.6, we recommend alligator straps with vegetable tanning for an elegant aesthetic that contrasts with the sport character, or vintage calf leather for sophisticated daily wear. For frequent water use, a rubber or NATO textile strap ensures practicality and durability. Browse our 20mm strap collection to discover all available options.

The strap is changed by removing the two lateral pins (spring bars) with a dedicated tool, available in quick-change kits. The pins on your Longines are standard for the 20mm size. If you are not experienced, the Casati Milano atelier offers a changeover service and can advise you on colour matching during a personalised session.

Yes, fully compatible. Any 20 mm strap installs correctly thanks to standard pins. Always verify that the pins are length-adjustable (some models require calibration), especially for rigid leather straps. Milano Straps offers a wide range of 20mm straps already tested on sports watches like this one.

A quality leather strap (alligator or calf with vegetable tanning) lasts 2–4 years with regular rotation, longer if worn occasionally. Lifespan depends on humidity, sun exposure and tanning method. Milano Straps straps are crafted from certified leather and a patina that improves with ageing. Casati Milano offers an 18-month guarantee on bespoke straps.
