The Seiko 7T92 calibre is a celebrated workhorse in modern analog quartz design, engineered specifically for high-speed sports timing. It delivers a highly dynamic triple-register layout featuring a blazing-fast 1/20th-of-a-second sub-dial at 12 o'clock, a running small seconds indicator at 9 o'clock, and a highly functional dual-hand elapsed counter at 6 o'clock that measures both minutes and hours up to a full 12-hour limit.

Because this calibre drives an immense variety of popular Seiko SND-series sports and aviation chronographs, clean factory replacement modules are in high demand. Over the years, thousands of original watches have suffered internal electronic circuit failures due to dead batteries leaking acid onto the mainboard. This virgin, pristine factory component features completely immaculate circuit tracks and brand-new stator coils, making it the perfect plug-and-play engine to fully restore an elite watch to factory specifications.

100% pristine and unhandled. Completely free of the tool scratches, gear tarnish, or terminal wear common on salvaged, used parts donor movements stripped from old cases.

This is a genuine Seiko movement featuring official factory stamping, ensuring direct compatibility and maintaining alignment with elite collector references over generic unbranded alternatives.

As this is genuine vintage New Old Stock from climate-controlled warehouse storage, a fresh high-quality battery (SR927SW) will be required upon installation. It includes the original temporary winding stem.
