Strap for DB25 Moon Phase Starry Sky White Gold / Diamond

The lug width of the DB25SJWS1 is precisely 20 millimetres. This measurement is calculated internally between the upper and lower lug attachment points, excluding entirely any crown depth. It is critical to verify this dimension with a calliper before ordering a strap, as even minor variations will compromise proper strap seating on the case.

For the DB25SJWS1, natural alligator or vegetable-tanned calf leather represent the most coherent selections: the former develops patina in parallel with the white gold case, whilst the latter guarantees elasticity and visible ageing. Structured rubber remains ideal for those who prioritise water-resistance and daily versatility whilst maintaining the aesthetic rigour of the case.

The strap is replaced via the spring bars—two small metal pins located inside the lug seats. One must use a professional spring bar tool to compress the pin slightly, then extract the exhausted strap and position the new strap in both seats. For watches of significant value, professional watchmaker assistance is recommended.

Any strap featuring a 20mm lug width is compatible with the DB25SJWS1, provided it is manufactured by reputable houses guaranteeing constructive tolerance within ±0.5mm. Milano Straps offers a dedicated collection of straps in alligator, calf, rubber and NATO, all certified for this dimension, with options for chromatic personalisation and finishing.

A quality leather strap—alligator or vegetable-tanned calf—maintains structural integrity between 3 and 5 years with daily wear, provided regular maintenance occurs. Wear acceleration depends upon prolonged solar exposure, constant relative humidity and wearing frequency. A watch of this calibre deserves rotation between at least two straps to extend significantly the longevity of each.
