The DB16 DB16PS2, seen from the bench

The De Bethune DB16PS2 is a platinum sports watch with a 43mm case housing the DB2509 calibre, featuring a tourbillon with integrated escapement, perpetual calendar, jumping seconds, power reserve indicator, and moonphase. The 18mm lug width is proportioned to the case diameter and requires precision-fitted straps due to integrated lugs with 0.5mm tolerance specifications. The platinum construction offers absolute durability and a patina that develops over time without aesthetic degradation.

Frequently asked questions

What is the lug width of the De Bethune DB16PS2?

The De Bethune DB16PS2 features a lug width of precisely 18mm. This dimension is proportioned to the 43mm case diameter and requires straps specifically calibrated to ensure perfect fit in the integrated lugs of the platinum case.

Which strap is recommended for the De Bethune DB16PS2?

For the DB16PS2, genuine alligator or vegetable-tanned calf are the most aesthetically coherent choices. Alligator creates a fascinating contrast with platinum, whilst calf develops a natural patina over time. For a contemporary approach, anthracite-grey rubber amplifies the avant-garde character of the design.

How do I change the strap on a De Bethune DB16PS2?

The DB16PS2 features integrated lugs within the case, differing from traditional spring bars. Strap replacement requires specialised tools and precise knowledge of the lug geometry. It is advisable to consult an authorised De Bethune service centre or a specialised workshop such as Atelier Casati Milano to avoid damage to the platinum finishing.

Can I use an aftermarket strap on the De Bethune DB16PS2?

Yes, but with meticulous attention. The strap must be custom-made for the precise configuration of the 18mm integrated lugs on the DB16PS2. Generic 18mm straps may not guarantee correct fitting. Milano Straps offers dedicated personalisation for this model, with prior technical compatibility verification.

What is the average lifespan of a leather strap on a luxury watch such as the DB16PS2?

A premium-quality leather strap (alligator, calf, shell cordovan) subjected to daily use and regular maintenance typically lasts 4-6 years. Durability increases significantly by reducing exposure to moisture, perspiration and direct sunlight. Vegetable-tanned calf tends to last longer, developing a natural patina that enhances aesthetics over time.
