Its Calibre 526-5 movement uses a sealed pressure capsule to convert small temperature fluctuations into energy, which is transferred through the winding mechanism to maintain tension in the mainspring. The movement incorporates a torsion pendulum designed for extremely low energy consumption. \u003cspan class=\"contents\"\u003e\u003cspan class=\"\"\u003e\u003c\/span\u003e\u003c\/span\u003e\u003cspan class=\"PDq2pG_selectionAnchor\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp dir=\"auto\"\u003eThe 526-5 was produced across multiple decades and is found with variations in case finish, dial configuration, and production details.
