This Omega Seamaster 300M 234.30.41.21.03.002 pairs a 41mm 316L stainless steel case with a matte blue sandwich dial and matching blue anodized aluminum bezel insert. It runs on clone caliber 8912 with a true no-date time-only layout, domed sapphire crystal with inner AR coating, and a stainless steel bracelet with alternating finishes and a foldover clasp.
Seamaster 300 Heritage Layout in 41mm Steel
This configuration of the Omega Seamaster 300M 234.30.41.21.03.002 is built around a 41mm case in 316L stainless steel. The case is listed at 13.2mm thick and paired with a stainless steel bracelet, giving this reference the balanced, substantial profile expected from this specific build. The bracelet uses alternating finishes and closes with a foldover clasp, keeping the overall presentation consistent from case to wrist.
The watch is also noted at 169.3 grams, which reinforces the solid steel construction across the head and bracelet. For buyers focused on this particular reference, those numbers matter because they define the exact presence of the watch rather than a generic Seamaster format.
Matte Blue Sandwich Dial and Aluminum Bezel
The dial is one of the clearest points of distinction on this model. It uses a sandwich construction with a recessed lower layer and a matte blue upper dial. The lower plate is coated with vintage-toned luminous material visible through the dial cutouts, creating the layered look associated with this configuration.
That matte blue dial is matched with a blue anodized aluminum bezel insert. The use of aluminum is a defining detail here, giving the bezel the correct non-ceramic look for this reference. The bezel is also described with a vintage lume pip, tying its visual character directly to the rest of the watch rather than treating it as a separate design element.
Clone Caliber 8912 True No-Date Movement
Inside is clone caliber 8912, built as a true no-date movement. That means the watch keeps a time-only display without an unused ghost date position at the crown. For this model, that is an important functional detail because the operation remains consistent with a dedicated no-date layout rather than a modified date base left with extra crown travel.
The movement is listed with an approximate 36-hour power reserve. It is also described with decorative plates intended to mirror the visual style of the caliber used by the original reference, giving the movement the right overall presentation while maintaining the no-date format that defines this watch.
Domed Sapphire and Steel Bracelet Finish
The crystal is specified as domed sapphire with inner AR coating. That crystal profile works directly with the vintage-leaning dial and bezel combination, while the anti-reflective treatment supports a cleaner view into the layered blue dial underneath.
The stainless steel bracelet continues the watch's material consistency and uses alternating brushed and polished surfaces. Combined with the 41mm steel case, domed sapphire crystal, matte blue sandwich dial, and blue anodized aluminum bezel, this reference stays tightly focused on the features that make 234.30.41.21.03.002 recognizable in its own right.
