The Omega Seamaster Planet Ocean Ultra Deep Summer Blue, reference 215.32.46.21.03.001, is the rubber-strap version of OMEGA’s 45.5 mm O-MEGASTEEL dive watch. OMEGA specifies water resistance to 6,000 m (20,000 ft), an automatic caliber 8912 with a 60-hour power reserve, and a Taiwan-listed price of NT$420,000 as of October 5, 2026. Those are manufacturer specifications and a regional listing—not independent test results or a universal price.
Which Summer Blue Ultra Deep is this?
Reference 215.32.46.21.03.001 identifies the blue-dial Ultra Deep with a rubber strap and O-MEGASTEEL buckle in OMEGA’s Seamaster Planet Ocean Ultra Deep collection. OMEGA’s catalog also includes other Ultra Deep configurations, including bracelet models and a titanium model with a NATO strap; their parts and specifications should not be attributed to this reference. For a listing or price check, use the full reference and confirm that the strap configuration matches.

What does the 6,000 m rating mean?
OMEGA states a water-resistance rating of 6,000 m, equivalent to 20,000 ft. It is a manufacturer specification for the watch, not a recommendation to take it to that depth or an indication of the depth normally encountered in recreational diving. The rating alone also does not establish how a particular watch will perform after wear, impact, or servicing; the listing is not a substitute for condition-specific guidance from OMEGA or a qualified service center.

Movement, reserve, and magnetic resistance
The product page specifies an automatic OMEGA caliber 8912 and a 60-hour power reserve. OMEGA also describes the movement as Master Chronometer certified and resistant to magnetic fields above 1.5 tesla (15,000 gauss). These are the maker’s stated movement credentials, rather than results from an independent test of this individual watch.
Summer Blue design context
In its Summer Blue launch presentation, OMEGA frames the dial as a tribute to the mysteries of the deep ocean and describes the caseback as carrying a commemorative Seamaster engraving. That is the brand’s interpretation of the collection’s design. The official launch video was published on June 27, 2023: OMEGA’s Summer Blue presentation.
