This replica Seamaster 210624 44mm 1001 101001 extends the Diver 300M platform into chronograph territory with a 44mm case that adds two subdial registers and a tachymeter bezel to the familiar Seamaster architecture. The 210.62.44.51.01.001 reference uses a black dial with contrasting subdials at 3, 6, and 9 o’clock, wrapped in a case that shares the asymmetric design language of the time-only Seamaster but scales it up for the additional complication. This is not simply a larger Seamaster with extra hands. The case geometry, pusher guards, and crown placement all reflect a purpose-built chronograph layout.

Technical Overview

• Case diameter: 44mm
• Case thickness: approximately 16mm
• Dial: black with luminous hour markers and three subdials
• Bezel: ceramic with tachymeter scale
• Crystal: sapphire with anti-reflective treatment
• Functions: chronograph, date, diving bezel
• Bracelet: integrated rubber strap with deployant clasp

The tachymeter bezel replaces the standard dive-time scale, signaling that this reference prioritizes timing events over submersion depth. The 44mm case accommodates the chronograph module without feeling overbuilt on wrists above 17cm circumference.

Inside the Movement

The chronograph mechanism in this reference operates through a column-wheel system, delivering precise start-stop-reset action without the rubbery pushback of cam-actuated alternatives. The omega seamaster chronograph configuration maintains a central seconds hand for elapsed time, with running seconds relocated to a subdial. Power reserve sits in the 50-hour range, standard for this caliber family. The date window at 6 o’clock uses a quick-set function accessible through the crown. For a different take on the Seamaster platform, compare this against the 600M Planet Ocean 45.5mm limited edition in the Seamaster collection.

What Sets It Apart

Most Seamaster 300M references are pure dive watches. This one adds a timing complication and wears larger as a result. The 44mm case and 16mm height put it in the same wrist-presence category as a Planet Ocean, but with the wave-dial aesthetic and helium escape valve of the 300M family. If you want Seamaster design language in a chronograph package, the 210.62 is one of very few options. This replica Seamaster 210624 44mm 1001 101001 delivers that rare combination of dive-ready construction and chronograph functionality.
