Description
At 44mm with a two-tone rose-gold-and-steel construction, this super clone takes the Diver 300M chronograph into mixed-metal territory. The black wave dial and black ceramic bezel create contrast against the Sedna gold bezel ring, crown and chronograph pushers that Omega uses on the genuine 210.20 references. Two-tone dive watches are uncommon, and the gold-and-steel approach gives the Diver 300M a visual weight that full-steel versions at the same diameter do not carry.

Sedna gold is Omega’s proprietary rose-gold alloy containing palladium, which resists color fade over time better than standard 18k rose gold. The gold elements appear on the bezel rim, the crown and the chronograph pushers. There are no gold bracelet links on this configuration, because it rides on black rubber rather than a two-tone bracelet.
Design & Finishing
The two-tone construction demands precise finishing where steel meets gold-tone surfaces. Against black rubber the Sedna gold reads warmer than it does on a two-tone bracelet, because no polished steel sits beside it competing for light. The black dial provides a dark canvas that makes the gold hands and indices appear more luminous, especially under indoor lighting. The helium escape valve at 10 o’clock signals professional dive-tool intent despite the dressier two-tone presentation. For a lighter all-titanium alternative, the 210.90.42.20.01.003 offers a more understated profile. Both are found within the Seamaster collection. The same two-tone chronograph on the steel-and-Sedna-gold bracelet is listed separately as the bracelet version of 210.20.44.51.01.001, which wears heavier and reads dressier than this rubber configuration.
On the Wrist
The rubber strap takes weight off a case that already carries gold, so this configuration wears noticeably lighter than the same reference on a two-tone bracelet. The black-and-gold combination reads dressy enough for evening wear yet retains the Diver 300M’s tool-watch credentials through the ceramic bezel and depth rating. The rubber is moulded with a raised central rib and side channels, so it lies flat on the wrist instead of bridging across the tendons. This two-tone chronograph on rubber delivers that two-tone Seamaster aesthetic for collectors who find all-steel Diver 300Ms too understated for their rotation.
