Best Omega watches under $7,500

50 current Omega references list for under $7,500 in the US. These are the strongest on paper, with no more than two from any one model family.

As an Amazon Associate we earn from qualifying purchases. Picks are based on brand-published specs, not paid placement. How we make money.

How we picked

Each watch earns points from published specs only: sapphire crystal (2), water resistance of 200 m or ISO 6425 diver certification (2; 100 m earns 1), screw-down crown (1), power reserve of 70 hours or more (1), display caseback (0.5), hacking plus hand-winding (0.5) and lug-to-lug of 47 mm or less (0.5). We rank by points, then by lower US list price. Near-identical colourways are grouped and we show the lowest-priced one. We cap each model family at two picks so the list isn't one watch in six colours.
