The Omega Seamaster Planet Ocean 6000M Ultra Deep has the higher stated water-resistance rating: 6,000 m (20,000 ft), compared with 3,900 m (12,800 ft) for the Rolex Oystersteel Deepsea ref. 136660. That 2,100 m difference is the clearest specification contrast, but it does not by itself decide which is the better watch for you. Case size, material, wearing setup and the exact variant matter just as much.

Which watch is rated deeper?
Omega’s Ultra Deep rating is 6,000 m, while Rolex lists the Deepsea at 3,900 m. The difference is 2,100 m in the manufacturers’ stated ratings. These are product ratings, not a recommendation that recreational divers need either depth capability.
There is a separate pressure-testing figure for the Rolex. Rolex describes its Ringlock case architecture and says the Deepsea is tested 25% beyond the depth shown on its dial. Its feature page states: “The Rolex Deepsea is, therefore, tested at 4,875 metres (16,000 feet).” That is Rolex’s account of its own testing, not an independent head-to-head test against Omega.

- Aftermarket Product: This is an aftermarket/generic made to original factory specs for a precise fit.
Omega’s steel listing says the 6,000 m model complies with ISO 6425:2018. This is a different manufacturer statement from Rolex’s test-depth claim, so the two should not be treated as equivalent measures or direct comparative test results.
How large are they, and how might they wear?
The Rolex case is 44 mm across; both sourced Omega variants are 45.5 mm. Diameter is only one part of fit. Omega publishes a 51.90 mm lug-to-lug measurement and 18.12 mm thickness for the steel model. The cited Rolex and titanium listings do not state comparable measurements, so those figures should not be transferred to the other watches.

The Rolex comes on an Oystersteel bracelet with Glidelock adjustment. The Omega steel model has a bracelet with a diver extension, while the sourced titanium reference is shown on a NATO strap. Material and wearing setup can change the feel on the wrist, and the available specifications do not establish which is more comfortable or lighter. Try the exact reference and strap or bracelet configuration if fit is decisive.
Movement, certification and magnetic resistance
Rolex lists calibre 3235 with approximately 70 hours of power reserve and a -2/+2 seconds-per-day precision specification after casing, as well as Superlative Chronometer certification. Omega lists calibre 8912 and 60 hours of reserve for the steel Ultra Deep; its manual gives the same movement and reserve for the titanium reference. A reserve figure describes how long a fully wound watch is specified to run, not its accuracy in an individual example.

Omega describes the Ultra Deep as Master Chronometer certified and says the movement is unaffected by magnetic fields of 1.5 tesla (15,000 gauss) or more. Those are Omega’s claims; the cited information does not establish that Rolex lacks magnetic resistance or provide a basis for treating the brands’ certification systems as directly equivalent.
Which one should you choose?
Choose the Omega Ultra Deep if
- The higher manufacturer-stated depth rating is your priority.
- You want to choose between the O-MEGASTEEL bracelet version and the titanium NATO-strap reference.
- You value Omega’s stated ISO compliance for the steel listing or its Master Chronometer and magnetic-resistance statements.
Choose the Rolex Deepsea if
- You prefer the 44 mm Oystersteel case and Oyster bracelet with Glidelock adjustment.
- The stated approximately 70-hour power reserve and Rolex’s published precision specification are relevant to your choice.
- You want Rolex’s Ringlock construction and its stated 4,875 m pressure-test figure.
Neither specification sheet establishes subjective comfort, value retention, comparative reliability or actual accuracy in a particular watch. Consider case thickness and total weight alongside diameter, then compare bracelet or strap preference, adjustment range, service access and budget. The official specifications do not determine a universal winner.
