Strap for Chronomat Automatic 36 South Sea Stainless Steel / White Gold / Diamond / Ice Blue

The lug width of the Breitling Chronomat 36 G10380591C1S1 is 18mm. This measurement refers to the internal distance between the two lugs at the strap attachment point. It is essential to verify this with a digital calliper before purchasing an aftermarket strap, as other Chronomat references of different case diameters may have different lug widths.

For the Chronomat 36 G10380591C1S1 in white gold and stainless steel, a vegetable-tanned alligator strap with central grain is the most coherent choice given the piece's positioning: the natural texture complements the rider tab bezel and the bi-material case finishes. Alternatively, shell cordovan in navy or cognac develops a luminous patina that particularly flatters white gold. For a more sporting use, a shaped rubber strap preserves the Chronomat's aviatic character.

To replace the strap on the Chronomat 36 G10380591C1S1, use a thin-tipped or forked spring bar tool, inserting it into the spring bar slot located on the inner side of the lug. By compressing the spring bar, the strap releases laterally. Care must be taken not to scratch the white gold case finishes: protecting the lug area with microsuede tape during the operation is strongly recommended. The new 18mm strap is fitted by compressing the spring bar and engaging it into the opposite lug.

Yes, any strap with an 18mm lug width and a straight or slightly curved end profile is compatible with the Chronomat 36 G10380591C1S1. Milano Straps offers a selection of handcrafted 18mm straps in alligator, calf leather, shell cordovan and rubber, manufactured with finishes and thicknesses calibrated to fit the Chronomat's lugs without tolerance play. For an optimal fit, straps with a low-profile end section are preferable to respect the case geometry.

The longevity of a leather strap depends on the material, tanning method and frequency of use. A vegetable-tanned alligator strap, maintained regularly with a neutral leather conditioner, retains its structural and aesthetic integrity for 3 to 5 years of daily wear. Shell cordovan, owing to the density of its leather fibres, can last over 5 years whilst developing an increasingly refined patina. Milano Straps warrants its straps for 18 months against manufacturing defects, providing additional assurance on the investment.
