Omega Seamaster Replica Collection
Three families define the Seamaster range. Diver 300M delivers a ceramic-bezel wave-dial diver rated to 300m. Planet Ocean pushes depth to 600m with a heavier, tool-oriented build. Aqua Terra strips away dive hardware for a thinner dress-sport crossover. All 92 references here are 1:1 super clone builds with ceramic bezels, sapphire crystals, and Co-Axial 8800 or 8900 calibers — shipped worldwide with full presentation box set.
The Seamaster is Omega's most diverse collection, and that range is exactly what makes choosing a reference less straightforward than it looks. The three sub-families — Diver 300M, Planet Ocean, and Aqua Terra — share a name but occupy very different spots on the wrist.
Diver 300M (ref 210.30.42.20) is the volume leader for good reason. At 42 × 13.56mm with a ceramic wave-pattern dial, it hits the sweet spot between tool watch and daily wearer. The helium escape valve at 10 o'clock is functional, the bracelet polishes up well enough for a suit, and the Cal 8800 inside delivers 55 hours of power reserve. If someone asks which single Seamaster to start with, this is the answer nine times out of ten.
Planet Ocean steps everything up. The 600m depth rating comes from a thicker case (43.5 × 14.3mm on the standard model), Liquidmetal ceramic bezel, and screw-down crown with additional gasket protection. Movement is the Cal 8900 — same Co-Axial architecture, but with a free-sprung balance and 60-hour reserve. It is heavier, bolder, and clearly built for buyers who treat depth specs as more than marketing. The 39.5mm reference (ref 215.30.40.20) is worth knowing about — it brings Planet Ocean proportions down to a size that works on 6.5-inch wrists.
Aqua Terra is the outlier. No dive bezel, no helium valve, no wave dial — just a clean teak-pattern face, a date window at 6, and a case that measures under 12mm thick. It is the watch for buyers who like what Seamaster represents but want something closer to a Constellation in terms of daily versatility. The 38mm version on bracelet is one of the thinnest Omega options this side of De Ville.
All 92 references here are built as 1:1 super clones — ceramic bezel inserts, sapphire crystals front and back, laser-engraved casebacks, and solid-link bracelets with the same clasp geometry as genuine production. Movement finishing replicates Geneva Wave patterns visible through the exhibition caseback. If you want chronograph functionality instead of a dive watch, the Speedmaster collection covers that space with the Moonwatch and Dark Side of the Moon.
Frequently Asked Questions
Everything you need to know about the Seamaster collection
Diver 300M (ref 210.30.42.20) is 42 × 13.56mm, rated to 300m, with the wave-pattern ceramic dial, Cal 8800, and polished bracelet links. Planet Ocean is 43.5 × 14.3mm, rated to 600m, with Cal 8900, a Liquidmetal ceramic bezel, and a screw-down crown. For daily wear the Diver 300M is lighter and thinner. Planet Ocean suits buyers who want maximum depth rating and a bolder tool-watch presence on the wrist.
Aqua Terra comes in 38mm — ideal for wrists around 6 inches and one of the thinnest Omega options outside the De Ville range. Diver 300M at 42mm works down to about 6.5 inches without overhang. Planet Ocean starts at 39.5mm (ref 215.30.40.20), surprisingly wearable despite the 600m depth rating. Avoid the 45.5mm Planet Ocean below 7.5-inch wrists.
Not at all. Polished center links on the bracelet and the wave-pattern ceramic dial read as design details, not sport features, from across a conference table. At 13.56mm thick the case clears shirt cuffs cleanly. The Constellation is dressier, but the Diver 300M is one of the few dive watches that genuinely crosses into suit-and-tie territory without looking out of place.
Diver 300M and Aqua Terra use the Co-Axial Cal 8800 — automatic, 55-hour power reserve, Master Chronometer rated to 15,000 gauss. Planet Ocean uses Cal 8900 with a free-sprung balance and 60-hour reserve. Both feature silicon balance springs and Geneva Wave finishing visible through the exhibition caseback. The Speedmaster uses a different architecture — manual-wind Cal 3861 in the Moonwatch.
Every Seamaster ships as a 1:1 super clone build: ceramic bezel insert, sapphire crystal, solid-link bracelet or vulcanized rubber strap depending on the reference, and laser-engraved caseback. The box set includes a branded Omega-style presentation case, warranty card, certificate of authenticity, and operating manual. Delivery is free worldwide with full tracking — typically 7 to 12 business days to the US and Europe, 10 to 15 days to Asia-Pacific.
