The DB25 DB25JLPS3V2, seen from the bench

The De Bethune DB25 Moon Phase Starry Sky Platinum is a haute horlogerie timepiece featuring a 44.00 mm platinum case with asymmetric architecture and 20 mm strap lugs. It houses the caliber DB2105V1 movement, displaying hours, minutes, and moon phase indication through internal finishes including decorated mainplate, visible rubies, and steel bridges. The model DB25JLPS3V2 represents De Bethune's independent watchmaking philosophy, combining mechanical complexity with three-dimensional time visualization via a floating platinum armillary sphere above a deep blue dial.

Frequently asked questions

What is the lug width of the De Bethune DB25 DB25JLPS3V2?

The lug width of the De Bethune DB25 DB25JLPS3V2 is 20 mm. This measurement refers to the distance between the two horizontal pins that attach the strap to the case, not the overall dial width. It is essential to verify this measurement before ordering a strap, as an incorrect lug width will not fit properly.

Which strap is best suited to the De Bethune DB25 DB25JLPS3V2 in platinum?

For a platinum case, alligator leather with natural tanning is the primary choice: the pronounced grain introduces a biological element that elegantly contrasts with the cold metallurgical geometry. Alternatively, vegetable-tanned calf offers patina that ages naturally over time, aligning with the patina platinum develops. For sportier contexts, a high-density NATO fabric in light grey or navy blue provides versatility without aesthetic compromise.

How do you change the strap on a De Bethune DB25 DB25JLPS3V2?

The change occurs via two replacement spring bars that insert into the lug pins. It is recommended to use a dedicated spring bar tool to avoid scratches on the platinum case. Position the spring bar in the lower crescent of the lug, press downward to release the spring, then remove the old strap and insert the new one. Casati Milano provides specialised assistance for this operation at their appointment-based atelier.

Are aftermarket straps compatible with the De Bethune DB25 DB25JLPS3V2?

Yes, provided the lug width is exactly 20 mm. Milano Straps offers artisanal compatible straps manufactured in alligator, calf, shell cordovan and technical fabrics. It is important to verify that the strap is free of curved spring bars or eccentric diameters, which could cause misalignment on the sculptural case of the DB25.

What is the lifespan of a leather strap for the De Bethune DB25 DB25JLPS3V2?

Lifespan depends on intensity of use, climate and material chosen. High-quality alligator with vegetable tanning typically lasts 3–5 years of daily wear before replacement, developing desirable patina in the meantime. Calf leather tends to wear more rapidly (2–4 years), whilst shell cordovan, if properly maintained, can exceed 7–8 years. NATO fabrics, less sensitive to wear, guarantee superior longevity unless fibre wear becomes apparent.
