Strap for DB25 Perpetual Calendar White Gold / Silver

The lug width of the De Bethune DB25 QPAWS1 is 20mm. This dimension is specific to the model and represents the outcome of the white gold case's structural design. To verify the compatibility of a strap, measure the distance between the two spring bar pins using a digital calliper: the value must be exactly 20mm. Straps of other widths (18mm, 22mm) will not fit correctly in the case lugs.

Alligator leather of Swiss or French quality, vegetable-tanned, represents the most aesthetically and functionally coherent choice. The natural grain of alligator creates a subtle dialogue with white gold, imparting a sense of chromatic cohesion. Hermès calf or equivalent vegetable-tanned alternatives offer a soft texture with lower initial rigidity. For sporty applications, an FKM rubber strap ensures moisture resistance. Canvas Cordura NATO offers a tactical and informal counterpoint to the formal character of the case.

To change the strap, use a high-quality spring bar removal tool with rounded tips to avoid scratching the white gold case. Position the tool beneath the spring bar, applying gentle upward pressure until the first end releases. Repeat the operation on the second bar. During removal, support the old strap to prevent it from falling and damaging the case. Insert the new strap by aligning the holes with the bars, ensuring that the decorative side (or marked side) faces outward. Press the bar until you feel a subtle click, indicating secure engagement.

Yes, any strap with a 20mm lug width is compatible with the DB25QPAWS1. However, we recommend purchasing straps from specialist suppliers (such as Milano Straps) that guarantee precise manufacturing tolerances and material quality. Generic or low-quality straps may present dimensions outside specification, causing unwanted lateral movement or stress on the white gold case lugs. Milano Straps offers customisable solutions, including white gold deployantes, to maintain the aesthetic coherence of your watch.

A high-quality alligator or calf leather strap, vegetable-tanned, has an average lifespan of 3–5 years with regular wear (4–5 times weekly). Longevity depends on environmental factors: direct sun exposure accelerates ageing, while constant humidity can compromise structural integrity. Vegetable tanning, though more delicate than chrome tanning, develops a protective patina over time. An FKM rubber strap can last 7–10 years without visible degradation. To extend the life of a leather strap, apply a specialist conditioner (free of silicones) every six months and store it in environments with 40–60% relative humidity.
