This is known as a “hi-beat” movement. This high frequency, nearly double that of a standard movement of the era, improves precision and gives the seconds hand a particularly smooth sweep.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the Zenith manufacture?\u003c\/strong\u003e\u003cbr\u003eFounded in 1865, Zenith is one of the oldest Swiss watch manufactures, and one of the few to have always produced its own movements. Decorated with a great many chronometry prizes, it is especially renowned for its El Primero automatic chronograph (1969), beating at 36,000 vibrations per hour.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs the movement mechanical or battery-powered?\u003c\/strong\u003e\u003cbr\u003eIt is entirely mechanical, hand-wound: it is wound each day via the crown, with no battery. Caliber 2562 offers a power reserve of approximately 50 hours once wound. It has been fully serviced and is guaranteed for 1 year.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the tritium indicated by “Swiss Made T”?\u003c\/strong\u003e\u003cbr\u003eThe “T” indicates that the original dial and hands use tritium as their luminous material, common on watches from the 1970s. Over time, tritium develops a warm patina much appreciated by collectors; however, its luminosity is no longer active, which is normal for a piece of this age.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs this watch suitable for a man or a woman?\u003c\/strong\u003e\u003cbr\u003eIt is a \u003cdiv data-glossary-id=\"520059\"\u003eunisex\u003c\/div\u003e watch.
