This 44mm Seamaster Diver 300M Chronograph pairs a blue polished ceramic dial with laser-engraved wave patterns and a blue ceramic bezel with integrated yellow gold scale details. Its clone 9900 movement drives the combined 12-hour and 60-minute chronograph display at 3 o’clock, with running seconds at 9 and a date at 6.
44mm Seamaster Diver 300M Chronograph in steel and yellow gold tone
This version of the Omega Seamaster Diver 300M Chronograph is built around the 44mm case of reference 210.20.44.51.03.001. The case is made from 316L stainless steel with 18K yellow gold plating applied to the crown, helium escape valve, and pushers. On the wrist, the watch presents as a full chronograph with the larger proportions and substantial mass that belong to this configuration, including a listed weight of 226g.
The bracelet continues the same two-tone layout in 316L steel and 18K yellow gold plating, finished with a deployant clasp. For buyers looking specifically for the steel-and-gold Seamaster chronograph format rather than a standard three-hand model, this reference stands apart through its heavier build and full bracelet execution.
Blue ceramic bezel with integrated yellow gold diving scale
One of the defining details here is the blue ceramic bezel with a yellow gold diving scale integrated into the ceramic surface. The scale is set flush into the bezel rather than sitting as a painted layer, giving this part of the watch a cleaner, more uniform finish. That combination of blue ceramic and yellow gold tone is central to the look of this reference and distinguishes it immediately from steel-only variants.
The bezel works with the rest of the two-tone case details to keep the visual balance consistent across the watch. With the gold-toned crown, helium escape valve, pushers, bracelet center links, and bezel scale all working together, the watch keeps a clear connection to the original reference it represents.
Blue polished ceramic dial with wave engraving
The dial is executed in blue polished ceramic and features laser-engraved wave patterns across the surface. That wave motif is one of the most recognizable elements of this Seamaster generation, and in this chronograph layout it sits behind a busier display without losing its presence. The dial furniture is matched with skeletonized gold-toned hands that stand out clearly against the blue background.
This watch also follows the reference-correct complication layout called out for this model: a combined 12-hour and 60-minute chronograph register at 3 o’clock, running seconds at 9 o’clock, and a date at 6 o’clock. The result is a dial that stays true to the specific layout of the 9900-style Seamaster chronograph rather than using a generic subdial arrangement.
Clone 9900 chronograph movement with combined 3 o’clock recorder
Inside is a clone 9900 chronograph caliber with an approximate 36-hour power reserve. The key detail is the architecture of the 3 o’clock subdial, where the 12-hour and 60-minute chronograph hands are combined on a single axis. This gives elapsed time reading a format specific to this movement style and separates it from more common modular chronograph layouts.
For buyers focused on function as much as appearance, that combined chronograph recorder is one of the strongest reasons to choose this reference. It preserves the distinctive display format associated with the original caliber design while keeping the rest of the dial balanced with running seconds at 9 and the date at 6.
Sapphire crystal and full sports-watch specification
The watch is fitted with imported sapphire crystal with a colorless anti-reflective coating. This keeps the dial presentation clear while maintaining the configuration listed for this build. The stated water resistance is 30 meters.
Altogether, this is a very specific Seamaster Diver 300M Chronograph execution: 44mm case, steel and yellow gold tone construction, blue ceramic bezel, blue ceramic wave dial, and a clone 9900 movement with the combined chronograph display at 3 o’clock. If this exact two-tone chronograph reference is what you want, the details here line up with the character of 210.20.44.51.03.001.
