About This Release

The Endeavour Perpetual Calendar Concept Tantalum combines H. Moser & Cie.'s minimalist design philosophy with one of watchmaking's most practical high complications.

Collector Note

Collectors may appreciate this release because it hides serious mechanical complexity behind an extremely clean dial. The tantalum case and tantalum sunburst dial make it feel more restrained and rarer than a typical perpetual calendar.

Collector Value

Limited to 50 pieces, this release should appeal to collectors who value independent watchmaking, rare case materials, and highly restrained complicated watches. The use of tantalum for both the case and dial gives it added collector interest.
