CALATRAVA MODEL, REF. 2508, MOVEMENT NO. 704'733, CASE NO. 689'983, MANUFACTURED IN 1955

With its strikingly balanced case architecture, reference 2508 stands apart from Patek Philippe’s more traditional time-only wristwatches and is widely regarded as one of the manufacture’s finest expressions of mid-century design. The reference represented Patek Philippe’s first serious attempt to create a waterproof case for a simple time-only wristwatch. Until then, the celebrated chronograph reference 1463, from which the 2508 inherited much of its robust aesthetic character, had been the manufacture’s principal waterproof wristwatch.

Its screw-down caseback, strongly downturned lugs and beautifully balanced dial proportions give the reference a confident and distinctly masculine presence rarely encountered among traditional Calatrava models of the period. The result is an unusual combination of classical Patek Philippe elegance and the purposeful construction more commonly associated with a sports watch. At its heart is the celebrated calibre 27SC, one of the manufacture’s most highly regarded centre-seconds movements of the era. Particularly interesting is the presence of a metal dust cap protecting the movement from moisture and magnetism, a practical feature more commonly associated with functional ‘tool’ watches.

This combination of technical robustness and refined design gives reference 2508 a distinctive position within Patek Philippe’s history. Retaining the elegance expected of a classic time-only wristwatch while incorporating the practical characteristics of a sports watch, it represents a fascinating meeting point between sophistication and functionality.
