Strap for Marine Torpilleur Stainless Steel / Grey / Bracelet

The lug width of the Ulysse Nardin Marine 1183-310-7M/42-BQ is exactly 21mm. This dimension is constructive and requires a proportionately sized strap of the same width to maintain the visual balance of the 42mm case. Measuring the lugs means positioning a digital calliper between the two inner shoulders of the case, where the strap anchors.

The best option depends on usage: an opaque alligator in medium grain amplifies Swiss quality; Italian calf leather tanned vegetally dialogues with the steel patina; a heavyweight cotton NATO or FKM rubber transforms the Marine into a daily-wear instrument. The choice depends on aesthetic context and desired wearing mode.

The change requires a specific tool (spring bar remover). Position the tool in the small lateral groove of the spring that supports the lug, push downward to release the pin. Remove the old strap and insert the new one, aligning it perfectly between the two lugs. Ensure the spring is firmly anchored on both sides.

Yes, provided the strap is dimensioned precisely at 21mm lug width. Quality artisanal straps are compatible if they respect this dimension. We recommend straps constructed with vegetable tanning or certified alligator to guarantee durability and aesthetic coherence with the watch's value.

A quality leather strap, tanned vegetally, lasts approximately 3-5 years with daily wear. Durability depends on climate, humidity, wearing frequency, and maintenance. Well-constructed Italian calf ages nobly, developing patina and natural texture. FKM rubber lasts longer but does not develop the characteristic aesthetic of ageing.
