Yacht-Master 126679SABR-0001— lug 20mm

The lug width of the Yacht-Master 126679SABR-0001 is 20 millimetres. This is the fundamental technical specification for purchasing a compatible strap: it must be measured precisely between the two attachment pins on the case. Even minor deviations create visual misalignment and abnormal stress on the buckle.

Alligator leather with vegetable tanning remains the most refined choice: the natural texture complements the Rolesium bezel and cognac or black colours amplify contrast with the white gold. Alternatively, vegetable-tanned calf offers inherent elegance and ages beautifully. For active sailing, a black or navy rubber strap guarantees resistance to salt water without compromising practicality.

Strap replacement requires specialist tools (quality spring bar tool, small nylon hammers). Position the watch on a stable surface, locate the attachment pins, apply gentle lateral pressure to extract them, and insert the new strap. It is advisable to entrust the operation to a professional to avoid scratching the case; Casati Milano offers this service as well.

Yes, provided it has a lug width of exactly 20 millimetres and has been tested on Yacht-Master models of the same generation. A bespoke handcrafted strap—such as those by Casati Milano—guarantees absolute compatibility and construction quality superior to OEM straps from minor brands.

A quality alligator or calf strap, subjected to preventive maintenance (monthly cleaning, conditioning every 6 months), lasts 4–6 years. If the watch is frequently exposed to salt water without immediate drying, durability reduces to 2–3 years. Rubber or nylon straps have greater longevity (7–10 years) if not exposed to direct UV rays.
