Prices by reference
Two price tiers run through Omega's Diver 300M catalog. The steel bracelet adds $400 at either tier.
| Dial | Steel on steel | US price | Steel on rubber | US price |
|---|---|---|---|---|
| Black | 210.30.42.20.01.001 | $6,700 | 210.32.42.20.01.001 | $6,300 |
| Blue | 210.30.42.20.03.001 | $6,700 | 210.32.42.20.03.001 | $6,300 |
| White | 210.30.42.20.04.001 | $6,700 | 210.32.42.20.04.001 | $6,300 |
| Grey | 210.30.42.20.06.001 | $6,700 | 210.32.42.20.06.001 | $6,300 |
| Green | 210.30.42.20.10.001 | $6,700 | 210.32.42.20.10.001 | $6,300 |
| Higher tier | 210.30.42.20.06.002 | $7,300 | 210.32.42.20.06.002 | $6,900 |
| America's Cup | 210.30.42.20.04.002 | $7,300 | 210.32.42.20.04.002 | $6,900 |
The cheapest way in is any of the five rubber-strap references at $6,300. Dial color costs nothing at the lower tier, so black, blue, white, grey, and green are the same money, and the choice is a matter of taste. The America's Cup edition is the one to price against its plain white sibling, since it costs $600 more on the bracelet. Omega also makes the Diver 300M in titanium, in gold, and in steel with gold, and those run well above this range.

Comparable Models
| Model | US price | Water resistance | Movement | Certification |
|---|---|---|---|---|
| Omega Seamaster Diver 300M | $6,300–$7,300 | 300 m | Calibre 8800 | METAS Master Chronometer |
| Rolex Submariner Date, ref. 126610LN | $11,350 | 300 m | Calibre 3235 | Superlative Chronometer |
| Tudor Pelagos, ref. M25600TN | $6,025 | 500 m | MT5612 | COSC |
| Christopher Ward C60 Trident Pro 300 | $1,095–$1,320 | 300 m | Sellita SW200-1 | None published |
The Submariner Date is a 41-mm watch with a 70-hour power reserve, and it costs $4,050 to $5,050 more than the steel Seamaster, depending on the configuration. The Pelagos is titanium, sits within a few hundred dollars of the rubber-strap Seamaster, and goes 200 metres deeper.
The C60 Trident Pro 300 matches the Omega's 300-metre rating at a fraction of its price. In its 40-mm size it stands 11.3 mm tall and 47.45 mm lug to lug, which makes it 2.26 mm thinner and 2.45 mm shorter than the Omega, though the Omega has 2 mm more case diameter. Christopher Ward reserves COSC certification for the bronze version.
On paper, the choice comes down to what the extra money buys. The Omega's premium over the Christopher Ward pays for the Calibre 8800, METAS certification, and 15,000-gauss magnetic resistance. Its discount against the Rolex comes with the same 300-metre rating and a certification Omega publishes for every steel reference above. The Pelagos is the closest on price, and the one to choose if the priority is depth or a titanium case.
