Strap for Longines Heritage L4.693.6.76.2

Alligator leather with vegetable tanning in saddle colour (natural dark brown) is the most coherent choice with the yellow gold case. The natural patina of the leather develops in parallel with that of the gold, creating a homogeneous chromatic effect over time. Alternatively, vegetable-tanned calf leather in cognac or shell cordovan offer chromatic versatility whilst maintaining material dignity. Avoid synthetic leather straps: they contrast with the value of the watch.

Yes, provided they respect the 18-millimetre lug width and construction quality. Artisanal straps from recognised brands (Hirsch, Barton, Molequin) are compatible. However, for a yellow gold watch, we recommend custom-made straps from specialist craftsmen such as Casati Milano: they guarantee personalised leather selection, perfect adaptation to the lugs and patina coordinated with the gold over time. Generic straps do not reflect the value of the piece.

A high-quality leather strap (alligator, calf or shell cordovan) lasts between 3 and 5 years with regular use and proper maintenance. Durability depends on exposure to UV rays, humidity and how frequently you wear the watch. A strap with vegetable tanning, such as those by Casati Milano, ages better and develops a patina that increases aesthetic value over time. To extend durability, apply a protective balm every 6 months and store the strap in a dry environment when not worn. Casati Milano offers an 18-month warranty on all artisanal straps.
