The Seamaster Diver 300M Summer Blue 210.30.42.20.03.003 pairs a 42mm 316L stainless steel case with a gradient blue ceramic PVD-treated dial and laser-engraved wave pattern under dual-sided AR-coated sapphire crystal. It runs on the VSF custom A8800 clone with quick-set date, hacking seconds, and an approximately 36-hour power reserve, finished on a brushed and polished stainless steel bracelet with micro-adjustable clasp.
Summer Blue gradient dial with engraved wave pattern
This 210.30.42.20.03.003 brings the Summer Blue configuration into the Seamaster Diver 300M format with a #003A70-toned blue ceramic PVD-treated dial. The color transition moves from a lighter center to a darker outer edge, giving this reference a distinct look within the range. Laser-engraved waves carry the familiar Diver 300M dial texture and remain visible through the gradient finish.
Over the dial, the watch uses sapphire crystal with dual-sided anti-reflective coating. That combination keeps the wave engraving and the changing dial tone clear from different angles while preserving the crisp, technical character of the watch.
42mm steel case with measured 13.4mm profile
The case is built in 316L stainless steel and measures 42mm across with a stated thickness of 13.4mm. This is the established Seamaster Diver 300M case format used for this edition, giving the watch the proportions expected from the reference. On the full steel bracelet, the watch is listed at 194.6g, adding a notably substantial overall build.
The case is matched to a solid commemorative Poseidon caseback. That closed back keeps the visual focus on the dial, bezel, and bracelet while staying consistent with this specific configuration.
Blue ceramic bezel with enamel diving scale
Framing the dial is a blue ceramic bezel fitted with a diving scale in Grand Feu style enamel. The use of ceramic keeps the bezel aligned with the dial's blue presentation, while the enamel scale adds a clean contrast that suits the technical layout of the Seamaster Diver 300M.
This bezel construction is one of the defining details of the watch. It complements the color of the dial without repeating the exact same surface effect, so the watch reads as layered rather than monochrome.
VSF custom A8800 clone with date and hacking seconds
Inside, this model is powered by the VSF custom A8800 clone caliber. The movement is built to mirror the architecture of the original A8800 style layout and is specified here with approximately 36 hours of power reserve. It also includes quick-set date and hacking seconds, two functions that matter in regular use and day-to-day setting.
The movement features the signature black balance wheel and correct jewel placement details described for this version. Although the solid caseback keeps the movement out of view, the operating functions remain central to the watch's appeal, especially for buyers looking for the specific A8800-based setup rather than a generic automatic substitute.
Steel bracelet with brushed and polished links
The bracelet is also made from 316L stainless steel and uses brushed and polished links for the alternating finish associated with this model. A micro-adjustable clasp completes the bracelet, giving the watch a more functional closing system than a basic fixed clasp arrangement.
With the steel case, blue ceramic bezel, gradient blue dial, and matching steel bracelet, this reference stays tightly focused on the commemorative Summer Blue specification. It is a distinct configuration with a measured case profile, a defined movement setup, and the exact dial treatment that sets this version apart.
