Christopher Ward C63 Sealander True GMT: Grand Release!

I’ve always had a soft spot for true GMT (traveler GMT) watches. There’s something incredibly satisfying about a watch that’s built for travel the way it was originally intended - where the local hour hand jumps independently, the date adjusts automatically, and switching time zones becomes effortless. It’s one of those complications that once you’ve used it, it’s hard to go back. There's certainly nothing wrong about a Caller (or Office) GMT movement, of course. But, my heart still prefers the True GMT movement.

So when Christopher Ward announced the C63 Sealander True GMT, it immediately caught my attention. Not just because it’s a new Sealander, but because it introduces the brand’s fourth in-house movement and finally brings a fully integrated traveller GMT complication to their lineup.

And after looking through the details, it feels like Christopher Ward might have built something very close to what I personally want in a GMT watch.

The Heart of the Watch: CW-002

Inside the C63 Sealander True GMT sits the new CW-002 calibre, which is quite different from their previous movements like the Calibre JJ04 in their elegant moonphase, the wild CW-003 of their C12 Loco, and their COSC-certified SH21 found in the C60 Trident, C65 Aquitaine, and others.

The key feature here is the true traveller GMT functionality. Unlike the more common “caller GMT” movements where the 24-hour hand is adjusted independently, a traveller GMT allows the local hour hand to jump forward or backward in one-hour increments without stopping the watch.

For anyone who travels frequently - or even just enjoys the practicality of the complication - it makes a huge difference. When crossing time zones, you simply adjust the local hour hand and the date automatically jumps when passing midnight, keeping everything perfectly synchronized.

It’s a complication that many enthusiasts consider the gold standard of GMT functionality.

The movement is also COSC chronometer certified, meaning it meets the strict -4/+6 seconds per day accuracy standard. On top of that, Christopher Ward has managed to pack in a 120-hour power reserve, thanks to a twin-barrel setup. Five days of autonomy is not just impressive on paper, as it means you can take the watch off for a long weekend, and it will still be running when you pick it up again.

A Dial That Shows Its Mechanics

One of the most interesting aspects of the C63 Sealander True GMT is how Christopher Ward has chosen to present the complication on the dial.

At three o’clock, the watch exposes the GMT bridge and wheel, giving the dial a more technical and mechanical personality. The bridge itself features a combination of linear brushing, sandblasting, and polished facets, while the circular brushed GMT wheel beneath adds visual depth.

Normally exposing parts of the movement on the dial can feel gimmicky, but here it actually works. The execution feels intentional and balanced rather than decorative.

The rest of the dial is surprisingly refined for something this mechanically expressive.

At six o’clock, an applied small seconds subdial adds symmetry, while a power reserve indicator at nine o’clock displays the movement’s five-day autonomy. Despite these additional elements, the dial remains clean and legible thanks to a multi-layer construction that creates depth and visual hierarchy.

Christopher Ward even invested in custom stamping tools to produce the grainé outer GMT track, giving the dial texture without the rippling that can sometimes appear in stamped finishes.

Inside the 24-hour ring, applied indices sit within a diamond-polished rhodium surround, while the markers themselves are linearly brushed with polished facets and filled with Super-LumiNova Grade X1 BL C1.

Even the hands follow the same finishing philosophy, with diamond-polished chamfers and brushed surfaces that catch the light just enough without becoming distracting.

The GMT hand and power reserve indicator are finished in either orange or blue lacquer, depending on the dial variant, adding a small but effective burst of colour.

A Movement That Took Years to Build

The CW-002 movement has been in development since 2023, overseen by Christopher Ward’s technical director Frank Stelzer. For him and the watchmakers, the challenge wasn’t simply adding a GMT function - it was integrating the complication without increasing the height of the movement.

To make this possible, the engineering team created a new plate to support the GMT wheel, allowing the additional components to fit within the existing architecture. In total, the project required 23 new or modified components, including 16 completely new parts and seven adapted from the earlier CW-001 calibre.

It’s the kind of engineering challenge that most brands solve by simply making the movement thicker. Christopher Ward chose to spend more time, money, and resources to develop a watch that wouldn't compromise on their values, instead.

The Sealander Case

The watch itself arrives in a 40.5mm Light-catcher case, a design that has become something of a signature for the brand.

At 14.15mm thick, the number might sound substantial at first, but a significant portion of that height comes from the box-domed sapphire crystals on both the front and back. Together they account for roughly 31% of the watch’s total height, which helps the watch appear slimmer on the wrist.

The stainless steel mid-case measures just 9.75mm and features a mix of fine linear brushing and polished accents.

Importantly, the watch still offers 100 metres of water resistance, keeping it firmly in the “daily wearer” category rather than something purely dressy.

Bracelet and Strap Options

Christopher Ward pairs the watch with its Bader bracelet, which features polished bevels along the outer links and a 6.5mm taper from lug to clasp.

The clasp includes a push-button micro-adjustment system with 6mm of adjustment, which is always a welcome feature for comfort throughout the day.

For those who prefer something sportier, the watch is also available with a colour-matched integrated rubber strap fitted with a deployant Bader buckle.

Two Variants at Launch

The C63 Sealander True GMT launches in two colourways:

• Silver-white dial with orange accents

• Black dial with light blue accents

Both offer slightly different personalities, but the underlying design and movement remain the same.

Pricing and Availability

The C63 Sealander True GMT will be released as part of Christopher Ward’s open series, meaning it will not be limited production.

Pricing starts at £2,895 / $4,200 / €3,950 on the integrated rubber strap, while the version on the Bader bracelet comes in at £2,995 / $4,350 / €4,090.

For a watch offering a COSC-certified in-house movement, a five-day power reserve, and a fully integrated traveller GMT complication, it positions the Sealander True GMT in a particularly interesting place within the market. Watches offering this level of functionality and movement development typically sit at significantly higher price points.

Christopher Ward True GMT: Is It Worth Your Attention?

As someone who genuinely loves true GMT watches, this release ticks a lot of boxes for me.

A traveller GMT complication, COSC certification, five days of power reserve, thoughtful dial design, and a versatile case size, and it's all packaged within Christopher Ward’s increasingly impressive in-house movement program.

For years, enthusiasts have been asking Christopher Ward for a true GMT (myself and the Watch Brief founders included), and the brand has clearly taken its time to get it right.

Looking at the final result, it’s hard not to feel like this watch might represent something close to the ideal modern GMT for everyday wear.

And if you’re anything like me - someone who believes a proper GMT should be built for travel first - then this is definitely worth your attention.
