It’s powered by the Calibre CH 27-70 Q manually-wound movement — Patek’s modified version of the Lemania Calibre 2310. Hand-finished and beautiful, it formed the basis for not only the 3970 - but also the Calibre .321 used in the earliest Omega Speedmatsers. \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-weight: 400;\"\u003eWhat is this notable movement powering?
