Patek Philippe · Manual Wind

25-21 REC PS

A rectangular hand-wound movement with small seconds, shaped so that plate and bridges fill a non-round case rather than leaving a round calibre rattling inside one. Patek introduced it in 2007 with the Gondolo reference 5098 — the company's first new shaped movement since the 9-90 of 1934. A Gyromax balance and Breguet overcoil regulate it.
