The right choice depends on the exact references, how they fit your wrist, and whether you want a date display—not simply the name on the dial. In this baseline steel comparison, OMEGA’s Seamaster Diver 300M is 42 mm and the Rolex Submariner 124060 is 41 mm; both are specified for 300 m water resistance. Try both if fit is decisive, then compare the specific dial, bracelet, movement, local price and seller before choosing.
Which references are being compared?
“Seamaster” and “Submariner” each refer to broader watch families, not one fixed specification. The cited OMEGA steel reference is the Seamaster Diver 300M 210.30.42.20.03.003; its official Japanese product page specifies a 42 mm case, calibre 8800 and 300 m / 1,000 ft water resistance: OMEGA product page.

The concrete Rolex comparison is the 41 mm Oystersteel Submariner 124060, a no-date model. Rolex lists calibre 3230, approximately 70 hours of power reserve and 300 m / 1,000 ft water resistance on its official US product page. These are reference-specific facts, not universal specifications for every Seamaster or Submariner.

How do size and fit differ?
The cited Seamaster is 42 mm across; the no-date Submariner is 41 mm. A one-millimetre difference does not by itself determine which watch wears smaller or better: case shape, lug geometry, bracelet and individual wrist all affect fit, and the available specifications do not establish a side-by-side wear comparison. Try the exact references on wrist, ideally on the bracelet or strap you intend to wear.

- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
Do you want a date display?
The Submariner 124060 has no date. If you prefer a date window, compare it with the distinct 41 mm Submariner Date 126610LN rather than treating the two Rolex references as interchangeable. Rolex’s official US page lists that Date model with calibre 3235, approximately 70 hours of power reserve and 300 m water resistance: Submariner Date product page.
OMEGA configurations also differ. The cited steel product page names calibre 8800, while OMEGA’s November 21, 2024 release described new 42 mm no-date Diver 300M models with calibre 8806. The release notes that the first Seamaster Diver 300M launched in 1993: OMEGA’s 2024 collection announcement. Check the reference rather than assuming every Seamaster has the same display or calibre.

What do the movements and dive specifications tell you?
| Reference | Movement and stated reserve | Water resistance | Other stated specification |
|---|---|---|---|
| OMEGA Seamaster Diver 300M 210.30.42.20.03.003 | Calibre 8800; reserve not stated on the cited page | 300 m / 1,000 ft | 42 mm; see OMEGA’s product page |
| Rolex Submariner 124060 | Calibre 3230; approximately 70 hours, according to Rolex | 300 m / 1,000 ft | 41 mm, no date, unidirectional 60-minute Cerachrom bezel; Rolex describes it as Superlative Chronometer certified. See Rolex’s US product page |
| Rolex Submariner Date 126610LN | Calibre 3235; approximately 70 hours, according to Rolex | 300 m / 1,000 ft | 41 mm; see Rolex’s US product page |
The shared 300 m rating is a specification, not proof of identical performance in every real dive situation. A watch does not replace dive training, a dive computer, manufacturer instructions or local dive procedures. Rolex’s feature page also describes the Submariner and Submariner Date as having unidirectional 60-minute Cerachrom bezels and luminescent displays: Rolex Submariner features.
What do they cost?
On the official US pages surfaced for this comparison, Rolex lists the Submariner 124060 at $10,050 and the Submariner Date 126610LN at $11,350. These are volatile list prices, not guaranteed transaction prices; check the live listing and seller at purchase time. The prices apply to the specified US references and should not be transferred to other regions or models.

A like-for-like current US list price for the cited all-steel Seamaster was not established. OMEGA’s Japanese site lists ¥2,189,000 for reference 210.20.42.20.03.001, a steel-and-yellow-gold model—not the all-steel 210.30.42.20.03.003. That regional two-tone price is not a valid direct price comparison: OMEGA Japanese product page. Compare current official prices for the exact material, functions and market you are considering.

Dial color, bezel, bracelet or strap, material and special-edition details can change the comparison. OMEGA announced six 42 mm James Bond and Spectre-themed Diver 300M models on October 5, 2026, with calibre 8806; treat these as special models, not as the baseline steel reference. Check the exact edition, availability and price on the OMEGA announcement.

Retail access is another practical distinction. Rolex states, “Only official Rolex retailers are allowed to sell and maintain a Rolex watch,” on its official US Submariner page. Use each brand’s official retailer channel and verify that a particular seller is authorized; availability can vary.

Which one is right for you?
- Choose the cited Submariner 124060 if you want the specific 41 mm, no-date configuration and its stated calibre 3230, approximately 70-hour reserve and Cerachrom bezel.
- Choose a Seamaster Diver 300M if a particular 42 mm configuration, dial, bracelet or movement variant fits your preferences; confirm the exact reference because configurations differ.
- Consider the Submariner Date 126610LN if you want a date display and are evaluating that separate reference, with its own price and calibre.
- For either watch, try the exact configuration, check current official pricing in your market and confirm the seller before buying.
