Omega Speedmaster Broad Arrow (Ref. 321.10.44.50.02.001)

The Omega Speedmaster Broad Arrow Ref. 321.10.44.50.02.001 is a distinctive automatic chronograph that combines classic Speedmaster design elements with a larger contemporary case, Omega’s Co-Axial technology, and a highly functional chronograph movement. Its substantial 44.25mm stainless-steel case gives the watch a bold wrist presence while maintaining the recognizable styling of the Speedmaster collection.

The silver dial features a vertically textured finish that adds depth and visual character. Applied hour markers and polished hands provide strong contrast against the dial, while the distinctive Broad Arrow-style hour hand pays tribute to the design language of early Speedmaster models.

The chronograph layout includes dedicated subdials for elapsed time and running seconds, while a date display adds practical everyday functionality. The combination of silver tones, polished accents, and contrasting dial elements gives the watch a refined yet sporty appearance.

Powered by the Omega Co-Axial Calibre 3313, the watch features an automatic mechanical chronograph movement with chronometer certification. The movement incorporates Omega’s Co-Axial escapement, designed to reduce friction within the regulating system and support consistent long-term performance.

The Calibre 3313 provides approximately 52 hours of power reserve when fully wound. It offers automatic winding, chronograph functionality, a date display, small seconds, and stop-seconds capability for precise time setting.

The movement displays central hours and minutes along with chronograph seconds, additional chronograph indications, running seconds, and the date. It can be viewed through the sapphire crystal exhibition caseback, allowing the wearer to appreciate the construction and finishing of the automatic Co-Axial chronograph movement.

The stainless-steel case measures approximately 44.25mm in diameter and approximately 14mm thick. Its polished and brushed surfaces create a combination of sporty character and refined finishing that complements the Speedmaster’s substantial case proportions.

A scratch-resistant sapphire crystal protects the dial and features anti-reflective treatment on the inner surface. The fixed stainless-steel bezel is engraved with a tachymeter scale, one of the defining functional and visual elements of the Speedmaster collection.

The tachymeter scale can be used together with the chronograph to measure average speed over a known distance, reinforcing the Speedmaster’s historical connection to motorsport and precision timing.

The watch offers water resistance of approximately 10 bar or 100 meters, making it suitable for regular everyday wear and occasional recreational water exposure.

Its matching stainless-steel bracelet continues the combination of brushed and polished finishing found throughout the case. The bracelet is secured by a stainless-steel folding clasp, providing a secure and comfortable fit while maintaining the watch’s sporty appearance.

This example is dated 2015 and is presented in very good pre-owned condition. It comes as a complete full set with its original Omega box and papers. Please review all photos carefully for an accurate representation of its cosmetic condition.

The Ref. 321.10.44.50.02.001 is an excellent option for collectors seeking a distinctive Speedmaster with automatic winding, Broad Arrow styling, a silver textured dial, exhibition caseback, Co-Axial technology, and a larger contemporary case size.
