Strap for Senator Automatic Red Gold / Diamond / Silver / Alligator / Pin

The lug width is exactly 20 millimetres. This dimension represents the historical standard of Grand Watchmaking for medium-sized cases and is determined by the precise distance between the two lugs located at the extremities of the case. To verify compatibility of an aftermarket strap, accurate measurement of this distance is essential, as even minor variations (18 or 22 mm) would compromise both mechanical and aesthetic fit.

For a rose gold Senator, alligator represents the most appropriate choice from both aesthetic and functional perspectives. The natural texture of alligator leather, with its characteristic scale pattern, dialogues elegantly with the polished rose gold case, creating a sophisticated tactile contrast. An alternative of equal standing is vegetable-tanned calf leather, which ages in parallel with the rose gold, developing a mature and conscious patina. For more sporting contexts, a NATO strap in canvas and leather remains a valid choice.

The Senator is equipped with screw-down lugs, which allow for quick replacement without special tools. Simply unscrew the lug pin gently from one side of the case using a small screwdriver, slide off the old strap, insert the new one (ensuring that the alignment holes coincide perfectly), and re-tighten the pin. The operation takes only a few minutes and remains within the capability of the informed enthusiast.

Any strap with exactly 20 millimetres lug width is compatible. On Milano Straps you will find a dedicated selection of straps in alligator, calf, shell cordovan, NATO canvas and structured rubber, all handcrafted and customisable according to colour and finish preferences. Mechanical compatibility is guaranteed, whilst the aesthetic choice remains a personal decision linked to context of use and preferred style.

A high-quality leather strap, treated with vegetable or refined synthetic tanning, has an average lifespan of 3-5 years under moderate daily use conditions. This variability depends on factors such as frequency of use, exposure to humidity, perspiration and climatic conditions. Seasonal rotation—alternating different materials according to the season—significantly extends the life of each individual strap. Periodic maintenance (gentle cleaning with a damp cloth, occasional conditioning with specific creams) helps to slow down natural ageing.
