De Bethune DB15 Perpetual Calendar Rose Gold DB15RT Box & Papers

The De Bethune DB15 Perpetual Calendar ref. DB15RT is an early and important expression of the brand’s classical side, pairing a high-complication perpetual calendar with a 43mm rose-gold case. It reflects the era when De Bethune was already blending traditional fine watchmaking with its own distinctive technical identity.

The white dial keeps the calendar display elegant and legible, while the rose-gold case gives the watch warmth, substance, and dress-watch presence. Compared with the brand’s more futuristic designs, the DB15 offers a more formal interpretation of De Bethune’s independent watchmaking philosophy.

On a leather strap, the watch has the feel of a serious complicated dress piece, but with the rarity and collector relevance that come from De Bethune’s early production.

This 2008 example is offered in pre-owned condition with box and papers. A complete rose-gold De Bethune perpetual calendar, it is a compelling piece for collectors who appreciate the manufacture’s earlier, more classical complicated work.
