It pairs a 45.5 mm case and matching bracelet with automatic calibre 8912, a 60-hour power reserve and a stated water-resistance rating of 600 bar (6,000 m / 20,000 ft). Those specifications describe a substantial professional-style dive watch; the exact reference matters because OMEGA lists other O-MEGASTEEL Ultra Deep configurations.
What is the O-MEGASTEEL Ultra Deep?
It is an O-MEGASTEEL version of OMEGA’s Seamaster Planet Ocean Ultra Deep 6000M. The specific example covered here is the blue-dial, bracelet-equipped reference 215.30.46.21.03.001. OMEGA’s catalog also includes other O-MEGASTEEL Ultra Deep references, so dial and bracelet or strap details should be checked against the reference number rather than assumed from the model name alone.

What O-MEGASTEEL means
OMEGA describes O-MEGASTEEL as a high-performance stainless-steel alloy produced through a pressure electro-slag remelting process. The brand says it has no nickel, increased nitrogen and manganese, a brighter appearance, non-magnetic character and corrosion resistance. These are manufacturer claims, not independent laboratory findings in the cited material.
OMEGA also states that O-MEGASTEEL is 40–50% harder than traditional steel. That comparison is OMEGA’s undated product-page claim, accessed in 2026; the cited source does not provide an independent test method or comparison. OMEGA’s material description
How to interpret the 6,000 m rating
OMEGA publishes the reference’s water resistance as 600 bar (6,000 m / 20,000 ft). This is the product’s stated rating. It should not be read as a substitute for dive planning, a depth gauge or other appropriate instruments.
OMEGA’s page for the related O-MEGASTEEL reference 215.30.46.21.03.002 says that model was tested to conform to ISO 6425:2018 for saturation-diving performance. Keep that statement tied to the .002 reference and its product page; it does not establish the same certification claim for .001. OMEGA listing for reference 215.30.46.21.03.002

How to compare O-MEGASTEEL Ultra Deep variants
OMEGA lists multiple O-MEGASTEEL Ultra Deep references. Compare the actual configuration rather than treating all versions as interchangeable.
- Reference and dial: confirm the full reference number and dial color.
- Bracelet or strap: check the supplied attachment and clasp configuration.
- Case dimensions: compare diameter, thickness and lug-to-lug where the exact listing states them. For .001, OMEGA lists 45.5 mm, 18.12 mm and 51.90 mm respectively.
- Movement and rating: verify the movement and water-resistance details on the page for that specific reference.
The listed dimensions provide useful figures for a fit comparison, but diameter alone cannot predict how a watch will wear on an individual wrist. The available cited material contains no comparative wrist-fit testing. The official catalog is the place to identify the listed O-MEGASTEEL configurations: OMEGA Ultra Deep catalog
