The DB25 DB25VRS3, seen from the bench

The De Bethune DB25VRS3 is a contemporary Swiss watchmaking landmark featuring the in-house DB2005 caliber. The rose gold case measures 42 mm in diameter with a lug width of 20 mm, designed with stratified architecture and geometric supports. The three-dimensional movement showcases hours and minutes with chronometric precision and refined finishing. The 20 mm lug width is calculated to create proportional balance between the case diameter and wrist attachment, essential for compatibility with specialized straps.

Frequently asked questions

What is the lug width of the De Bethune DB25VRS3?

The De Bethune DB25VRS3 features a lug width of 20 millimetres. This measurement, engineered by De Bethune, visually proportions the 42mm case to the wrist and determines compatibility with all aftermarket straps. To verify the correct measurement, position a calliper across the lateral attachment lugs, measuring the exact distance between the junction points.

Which strap is most suitable for the De Bethune DB25VRS3?

Alligator is the most discerning choice: its extremely fine grain does not compete with the case's geometry, whilst its natural patina develops in parallel with the rose gold over time. Alternatively, vegetable-tanned calf leather offers more pronounced texture and durability for daily wear, with patina darkening over time. Technical rubber presents a compelling contrast, emphasising the case's geometry with visual coherence. NATO straps offer the perfect compromise between lightness and versatility.

How do I change the strap on my De Bethune DB25VRS3?

Strap replacement requires a spring bar tool (a specific instrument for removing lugs). Position the tool beneath the spring bar (the small spring beneath the lug), pushing upward to free the pin. Once the original strap is removed, insert the new one by aligning the holes with the case's attachments, then lower the spring bar until it clicks into place. A delicate operation but not complex—achievable at home with patience and appropriate tools.

Is a 20mm aftermarket strap compatible with the DB25VRS3?

Yes, any strap with a 20mm lug width is compatible with the DB25VRS3, provided it is manufactured with professional tools and artisanal finishing. Milano Straps produces straps specifically for this measurement, available in alligator leather, vegetable-tanned calf, NATO and rubber. Compatibility is guaranteed by construction precision and the quality of spring bars employed.

What is the lifespan of a leather strap on the De Bethune DB25VRS3?

A quality leather strap, vegetable-tanned, typically lasts 3-5 years with moderate daily use. Longevity depends on intensity of use, perspiration, solar exposure and maintenance. Alligator tends to outlast calf slightly due to skin density. The patina that develops is not wear but natural ageing—a sign of a strap that narrates your wrist's history.
