Frequently asked questions

What is the lug width of the De Bethune DB25 DB25LWS1V1?

The De Bethune DB25 DB25LWS1V1 features a lug width of 20mm. Although this dimension is standard for many sports watches, in the case of the DB25 it is integrated into the case architecture with remarkable refinement—the curved lugs respect the spheroidal geometry of the dial. When replacing the original strap, it is essential to maintain this width to ensure correct alignment within the case structure.

What strap would you recommend for the De Bethune DB25 DB25LWS1V1?

For the DB25 DB25LWS1V1, we recommend high-quality leather straps, particularly vegetable-tanned calf or shell cordovan for those seeking aesthetic character. The geometric elegance of the spheroidal dial is enhanced by sober, tactilely rich materials: a dark leather with developed patina creates a fascinating contrast with the titanium case. Alternatively, a robust canvas NATO maintains the watch's technical character, whilst an FKM rubber strap offers sporty versatility without compromising constructive sophistication.

How do you change the strap on a De Bethune DB25 DB25LWS1V1?

The lug attachment of the DB25 DB25LWS1V1 requires care: the integrated case geometry means the lug is not removable through conventional means. Strap replacement must be performed by a specialist atelier that understands De Bethune architecture. In Milan, Atelier Casati Milano provides bespoke service: the technician removes the original strap via gentle spring bar extraction, installs the replacement whilst preserving original attachments, and verifies alignment with the dial. Never attempt this operation independently on watches of this complexity.

Are aftermarket straps compatible with the De Bethune DB25 DB25LWS1V1?

Yes, any strap with a 20mm lug width is physically compatible with the DB25 DB25LWS1V1. However, because the case features a particular geometry with a curved integrated lug, we recommend selecting straps specifically crafted for curved lugs, which ensure optimal adherence without anomalous tension. Milano Straps' artisanal straps, created using tailoring techniques, are available in 20mm width and customisable in material and colour; each is crafted with respect for the aesthetic proportions of high-calibre watches such as the DB25.

What is the expected lifespan of a leather strap on the De Bethune DB25 DB25LWS1V1?

A high-quality leather strap, subjected to regular wear (4-5 days weekly under normal conditions), maintains structural integrity for 18-36 months before showing signs of deterioration. This depends on the tanning method: vegetable-tanned calf ages elegantly, developing a rich patina, whilst shell cordovan maintains rigidity longer due to fibre composition. Exposure to humidity, direct sunlight, and thermal fluctuations accelerates ageing. A well-maintained strap—dried regularly and not left in damp environments—can significantly prolong functional and aesthetic life, becoming a visible witness to the time spent with the watch.
