The story
The Constellation's defining visual element, four claws set at the corners of the bezel, was introduced with the Constellation Manhattan in 1982, designed by Carol Didisheim in place of the traditional smooth bezel used on earlier Constellation models dating back to the line's 1952 debut. That claw design has carried through every subsequent Constellation generation, including the current one. Omega redesigned the men's Constellation line in January 2020, first releasing 36mm and 39mm sizes before adding the 41mm case reference 131.30.41.21.01.001 sits within. The update beveled the edges of the case, lugs, and claws, reshaped the winding crown, and gave the dial slimmer facetted indexes. The 41mm models also moved to the higher-capacity caliber 8900, a step up from the caliber 8800 used in the smaller 36mm and 39mm sizes. As the current flagship men's size in the collection, the 41mm steel Constellation sits alongside precious metal and two-tone variants that share the same case architecture.
What to check before you buy
Because Omega sells this 41mm case in numerous dial and bracelet combinations, distinguished only by the last digits of the twelve-digit reference, always match the complete reference number rather than relying on case size or dial color alone. Confirm the caseback shows caliber 8900 rather than 8800, since the smaller 36mm and 39mm Constellation models in the same 2020 generation use the lower-capacity movement despite a similar overall look. Inspect the claws and bezel edges for wear or replating on used pieces, as the claws are a raised, exposed design element that can pick up scratches over time. As with other current Omega Master Chronometer pieces, ask about service history on watches more than five to eight years old.

Common questions
Why does the Constellation have claws on the bezel?
The claws were introduced on the Constellation Manhattan in 1982 as a design choice by Omega in place of a plain bezel, and they have remained a signature element of the men's Constellation line ever since.
What movement does the 41mm steel Constellation use?
It uses the Omega Co-Axial Master Chronometer caliber 8900, an automatic movement with a 60 hour power reserve and METAS Master Chronometer certification.
How does the 41mm model differ from the 36mm and 39mm Constellation?
Beyond the larger case, the 41mm uses the caliber 8900 rather than the caliber 8800 found in the smaller sizes, giving it a higher magnetic resistance rating and a slightly different power reserve profile.
What is the water resistance of this reference?
It is rated to 50 meters, which is typical for a dress-oriented watch rather than a dedicated sports or dive model.
When was the current case design introduced?
Omega introduced this generation of the Constellation in 2020, redesigning the case, crown, claws, and dial indexes while keeping the four-claw bezel that has defined the line since 1982.
