Other steel references

The white dial also comes on a rubber strap (310.32.42.50.04.001) and a leather strap (310.32.42.50.04.002), each at $8,700.

Reference 310.30.42.50.01.004, at $10,400, is a newer steel-on-steel model with a black lacquered dial, white subdials, a black ceramic bezel ring with the dot over 90, sapphire on both sides, and a foldover clasp with a comfort setting. It is 13.54 mm thick.

Omega's catalog lists three more black-dial steel references: 310.30.42.50.01.002 on a steel bracelet with sapphire on both sides and a thickness of 13.18 mm, 310.32.42.50.01.001 on a coated nylon strap, and 310.32.42.50.01.002 on a leather strap.

Precious-metal variants

Beyond steel, Omega sells the Moonwatch Professional case in steel with gold and in solid gold, in three alloys: Moonshine Gold, Sedna Gold, and Canopus Gold, which is Omega's white-gold alloy. The two-tone references have a black ceramic bezel ring with the dot over 90 in Ceragold. On those two-tone watches, moving from the alligator strap to the matching bracelet costs $8,000. The Sedna Gold and Canopus Gold bracelet references have sapphire on the front and on the caseback, so they match the sapphire steel references on that point. Omega's catalog also lists Moonshine Gold on a rubber strap, and steel with Sedna Gold in the same two forms as the steel-and-Moonshine-Gold pair.

Price comparison across current Moonwatch Professional references

FAQ

Is every reference the same size? Every reference in the tables above is built on the 42-mm Moonwatch Professional case with the Calibre 3861 movement. Thickness changes with the crystal and the model: 13.54 mm on the Hesalite reference and 13.18 mm on the sapphire white-dial reference.

What is the cheapest way into a Calibre 3861 Moonwatch Professional? The Hesalite steel-on-steel reference 310.30.42.50.01.001 is the lowest-priced configuration in the tables above, at $7,800.

Hesalite or sapphire? Hesalite is the cheaper crystal here, and the reference at $7,800 pairs it with a solid caseback. The sapphire references add a display caseback, so the movement is visible, and the white-dial version costs $1,300 more.

Is the white dial more expensive than the black? Compared on the steel bracelet, yes: $9,100 for the white-dial reference against $7,800 for the black Hesalite one. Part of that difference is the sapphire on both sides of the white-dial watch.
