Strap for Master Collection 44 Retrograde Moonphase Stainless Steel / Silver-Roman / Bracelet

The lug width of the Longines Master Collection L2.739.4.71.6 is 22mm. This measurement is taken internally between the spring bars (from inner bar to inner bar), excluding the width of the bars themselves. It is a standard lug width for 44mm watches requiring aesthetic versatility across formal and everyday contexts.

For the Longines Master Collection L2.739.4.71.6, vegetable-tanned alligator is the most appropriate choice. The natural crocodile grain dialogues perfectly with the geometric precision of the dial, creating aesthetic harmony. Shades such as havana (dark brown), polished black, or tortoiseshell blue offer versatility whilst maintaining formal sophistication. Alternatively, vegetable-tanned cordovan calf leather ensures durability and dignified ageing.

To change the strap, you must remove the spring bars connecting the lugs to the case. Using a dedicated tool (spring bar tool), compress the inner bar, extract it from the seat, and withdraw the lug. Install the new 22mm strap by reversing the procedure: insert the compressed bar into the new lug, align with the lateral seats, and release to snap. If unfamiliar with this process, a specialised watch repair service will complete the operation in minutes.

Yes, any strap with a 22mm lug width is compatible with the Longines Master Collection L2.739.4.71.6. On milanostraps.it you will find a curated selection of artisan 22mm straps vegetable-tanned, in alligator, calf, NATO, and rubber. All are available in various shades and finishes, customisable to specific measurements, with the option to add initials or choose stitching thread colour.

The lifespan of a leather strap depends on tanning quality and usage patterns. A vegetable-tanned alligator or calf strap, if properly maintained, lasts 4 to 7 years before replacement becomes necessary. The patina developing over time is a desirable characteristic of vegetable tanning. Ageing accelerates with constant exposure to water, perspiration, and UV radiation. Casati Milano provides an 18-month warranty on all made-to-measure straps, guaranteeing artisanal craftsmanship and rigorous leather selection.
