Is your Admiral
the real deal?
The Corum Admiral is the brand's most recognized collection, defined by its distinctive 12-sided case and maritime signal flag hour markers. Its bold nautical design and luxury positioning have made it a popular target for counterfeiters producing superficially convincing replicas.
How to authenticate a Admiral
Maritime Signal Flag Markers
Each of the 12 hour positions features a specific international maritime signal flag. The flags must be painted or applied with precise, vibrant colors matching the actual maritime alphabet. Under magnification, color boundaries should be sharp with no bleeding. Each flag must be correctly oriented. Counterfeits frequently use wrong flag colors or patterns.
12-Sided Bezel and Case
The Admiral's dodecagonal (12-sided) case is machined with exacting precision. Each of the 12 flat facets must be identical in size and angle. The transitions between polished and brushed surfaces should be crisp. The bezel should sit flush with the case. Counterfeits have uneven sides with rounded or poorly defined edges.
Date Window Integration
The Admiral's date window is typically positioned at 3 o'clock with a clean frame that matches the dial color scheme. The date disc should have a properly sized font and the date change should occur precisely at midnight. Counterfeits have oversized or misaligned date windows with incorrect fonts.
Automatic Movement
The Admiral uses quality Swiss automatic movements, either ETA-based or Corum in-house calibers on higher-end versions. Through the case back, the movement should be properly finished with a signed Corum rotor. The timekeeping should be accurate. Counterfeits use undecorated generic movements.
Vulcanized Rubber Strap
Many modern Admiral models feature integrated vulcanized rubber straps with a textured pattern. The rubber should be supple and comfortable with precise molding. The strap integrates seamlessly with the 12-sided case. The deployment clasp should be signed. Counterfeits use stiff, generic rubber with poor integration.
Case Back Engravings
The Admiral's case back features precise engravings including the Corum key logo, model reference, serial number, and water resistance rating. On exhibition backs, the sapphire should be perfectly clear. All text should be laser-engraved with sharp, consistent depth. Counterfeits have shallow, blurry, or incorrectly formatted engravings.
Admiral counterfeit warning signs
Wrong Flag Colors or Patterns
Maritime signal flags follow a strict international standard. If any hour marker flag has incorrect colors, wrong stripe orientation, or non-standard patterns, the dial is counterfeit. Cross-reference each flag against the International Code of Signals.
Misaligned Dodecagonal Case
The 12 sides of the case should align symmetrically with the corresponding hour markers on the dial. If the case appears rotated relative to the dial or the facets don't align with the flags, the watch is poorly assembled or counterfeit.
Faded or Bleeding Flag Colors
Genuine Corum flags maintain vibrant, distinct color separation. If the flag colors appear faded, muddy, or are bleeding into each other, the printing quality is not genuine.
Loose Bezel Fit
The 12-sided bezel should be firmly seated with no play or movement. If the bezel wobbles, has gaps, or rotates when it should be fixed, the watch is counterfeit.

Frequently asked questions
What size is the Corum Admiral?
The current Admiral collection is available in 42mm and 45mm case sizes. The 42mm is the standard men's size and the most popular option. Despite the angular 12-sided shape, the Admiral wears comfortably due to its relatively slim profile and ergonomic lug design. The 45mm is positioned as an oversized sport option.
Is the Corum Admiral water resistant?
Yes, the Corum Admiral is water resistant to 100 meters (10 ATM) on most models, making it suitable for swimming and recreational water activities. Despite its nautical theme, it is designed as a luxury sports watch rather than a professional dive instrument. The screw-down crown and quality gaskets ensure reliable water protection.
What movement does the Admiral use?
The standard Admiral 42 uses a Swiss automatic movement, typically an ETA 2892 or Sellita SW300 base caliber. The Admiral Legend 42 and higher-end versions use Corum's in-house CO 395 automatic caliber. All movements are visible through the sapphire exhibition case back and feature appropriate Swiss finishing and Corum-signed rotors.
