Why there is no 45mm Globemaster
Omega lists the Constellation Globemaster at 39mm. The line has no 45mm reference. A listing that says "Globemaster 45mm" pairs a Globemaster dial with a larger case from another model, or it lists the wrong size. Ask the seller for a caliper photo of the case at 3 and 9 o'clock before you pay.
First pick: Planet Ocean 45.5mm
The Planet Ocean is the closest real Omega in the 45mm class. Case 45.5mm. Water resistance 600m. Ceramic bezel. Sapphire caseback. It gives the wrist presence the buyer of a "45mm Globemaster" is after, and the reference exists in the Omega catalog. Replica stock uses several movements. Ask for the caliber number and a photo of the balance wheel.
Option 2: Seamaster Diver 300M, 42mm
Case 42mm. Water resistance 300m. It sits lower on the wrist than the Planet Ocean. Pick this one if 45.5mm covers your whole forearm on a 6.5 inch wrist.

Option 3: Aqua Terra 41mm
Case 41mm. Thickness 13.2mm. Water resistance 150m. The dial reads closer to the Globemaster's pie-pan look than any Seamaster. This is the dressier pick.
Option 4: Globemaster 39mm
The correct size. Case 39mm. Water resistance 100m. If you want the actual Globemaster shape, buy the 39mm and skip the 45mm listings.
