Is your C63 Sealander
the real deal?
The Christopher Ward C63 Sealander is a Swiss-made GMT watch with British design. It features a true GMT complication powered by the Sellita SW330-2 movement. Here's how to authenticate a C63 Sealander.
How to authenticate a C63 Sealander
True GMT Functionality
The C63 Sealander features a true GMT complication with independently adjustable hour hand. Pull the crown to the second position and the local hour hand jumps forward/backward in one-hour increments while the GMT hand (24-hour) and minute hand continue running. Fakes often have non-functional GMT hands or "caller GMT" movements that move both hands together.
Bi-Directional 24-Hour Bezel
The C63 features a bi-directional rotating bezel with 24-hour markings and a ceramic insert. The bezel should rotate smoothly in both directions with precise clicks. The hour markers on the bezel should align perfectly with the dial hour markers. Fakes often have poorly aligned bezels or aluminum inserts instead of ceramic.
Twin-Flag Logo at 9 O'Clock
The C63 Sealander features the twin-flag logo (UK and Swiss flags) at the 9 o'clock position on the dial. The logo should be perfectly crisp and aligned. Check that the flags use the correct colors (Union Jack and Swiss cross) and that the logo is not blurry or crooked. This is a key authentication point.
Sellita SW330-2 GMT Movement
Open the exhibition case back to verify the Sellita SW330-2 automatic GMT movement. The rotor should have Christopher Ward branding, and you should see Swiss movement markings and the GMT module. The movement should have clean finishing with perlage or Geneva stripes. Fakes often use Chinese movements or basic ETA 2824 without GMT functionality.
Light Tube Hour Markers
Like all modern Christopher Ward watches, the C63 Sealander uses light tube technology with Super-LumiNova-filled tubes for hour markers. These should glow brightly and evenly in the dark with exceptional brightness and duration. The GMT hand should also be lumed. Fakes typically use painted lume that glows weakly or not at all.
Case Finishing & Details
The C63 Sealander uses a stainless steel case with polished and brushed finishes. Check for sharp beveled edges, consistent brushing, and smooth polished surfaces with no tool marks or uneven finishing. The screw-down crown should have the CW logo and screw down smoothly. The case back should have clean engravings including water resistance, serial number, and "Swiss Made."

Non-Functional GMT Complication
Test the GMT functionality by pulling the crown to the second position. The local hour hand should jump independently in one-hour increments while the GMT hand and minute hand continue running. If the hour and GMT hands move together, or if the GMT hand doesn't move at all, it's a fake with a basic movement.
Chinese Movement Instead of Sellita SW330-2
Open the exhibition case back—if you see a Chinese movement (e.g., DG2813, Seagull ST2130) instead of a Sellita SW330-2 with Swiss engravings and GMT module, it's fake. The rotor should have Christopher Ward branding and the movement should show quality finishing.
Incorrect 24-Hour Bezel Markings
The 24-hour bezel should have clear, evenly spaced markings for all 24 hours with a lume pip at 12/24. If the bezel has 12-hour markings instead, or if the 24-hour markings are uneven or blurry, it's counterfeit. Genuine C63 bezels have ceramic inserts with crisp printed markings.
Poor Logo Quality or Placement
The twin-flag logo at 9 o'clock should be perfectly crisp and aligned. If the logo is blurry, crooked, at the wrong position (e.g., 12 o'clock), or uses incorrect flag colors, it's fake. Genuine Christopher Ward logos are applied with precision and high-quality printing.

Frequently asked questions
What is the GMT function on the Christopher Ward C63 Sealander?
The C63 Sealander features a true GMT complication that displays a second time zone via a 24-hour hand and rotating 24-hour bezel. You can independently adjust the local hour hand (jumping hour) while the GMT hand and minute hand continue running. This allows you to track home time and local time simultaneously—ideal for travelers.
What movement does the C63 Sealander use?
The C63 Sealander uses the Sellita SW330-2 automatic GMT movement, a Swiss-made caliber with true GMT functionality. It features 25 jewels, 28,800 vph (4Hz) beat rate, hacking seconds, hand-winding, and approximately 42 hours of power reserve. The movement can be viewed through the exhibition case back.
How can I tell if my C63 Sealander is authentic?
Check for the twin-flag logo at 9 o'clock, bi-directional 24-hour bezel with ceramic insert, independently adjustable GMT hand, Sellita SW330-2 movement visible through exhibition case back, light tube hour markers, screw-down crown, and 'Swiss Made' at 6 o'clock. Fakes often have non-functional GMT complications, Chinese movements, and poor finishing.
