The ‘GMT’ function is one of the most popular complications in watchmaking. By using the fourth ‘GMT’ hand – which travels around the dial over 24 hours – it’s possible to tell the time in any timezone around the world accurately. GMTs have always been popular with Christopher Ward customers too, with models like the C60 Trident GMT 600 consistently among our best sellers.

With this, we’ve unveiled two new GMT timepieces – the C65 GMT Worldtimer and the C60 Elite GMT 1000. Both are fantastic watches. But which one is right for you?

This guide will help you make the right decision.

Pro diver or part-time dipper? 

If you want a professional diving tool, the C60 Elite GMT 1000 should be your first choice. Engineered from Grade 2 titanium – which has the highest strength-to-density ratio of any metal – it’s waterproof to 1000m. There’s also a helium release valve which will aid the release of harmful molecules as you ascend from an ultra-deep dive.

While the new C65 GMT Worldtimer isn’t primarily a diving watch, it’s still water-resistant to 150m – easily enough for all but the most ambitious of subaqua expeditions. And perfect if your idea of a dive involves popping into the deep end of your local swimming pool.

Retro chic vs modern tool watch

The inspiration for the C65 GMT Worldtimer’s design is the aeronautical watches of the mid-1960s. From the unfussy dial design to the vintage-style glass box crystal, this is a slim timepiece that will work with any outfit – and at 41mm wide it’ll suit all wrists.

The C60 Elite GMT 1000 is a vehemently modern watch. It’s countdown diving bezel is made of ceramic with Super-LumiNova®-filled numerals to ensure visibility in low light. Built to withstand the incredible pressure found at 1000m, it’s chunkier than the Worldtimer, and also a little larger, at 42mm across.

Battle of the bezels

As a pro-level diving watch, the C60 Elite GMT 1000 boasts a countdown bezel: a vital tool for timing your dive. But as this is a GMT, it also has something else: an inner “bezel” which you use with the fourth GMT hand to tell the time in another part of the world.

The C65 GMT Worldtimer also has two bezels, but the outer one features the names of international cities around the world. Say you’re in London but want to know the time in Tokyo. Line up ‘London’ on the bezel with the current time on the inner 24-hour bezel, and then search out ‘Tokyo’. It’ll correspond to the correct time. If you want to use the GMT to monitor the time in another timezone (say, New York), just set the fourth hand to its time on the inner bezel. It’ll always stay in step.

Different watches – same movement

If you value near-perfect accuracy, the Sellita SW330 GMT movement that powers both watches will be your trusted friend. Not only does it run a GMT function as a certified chronometer, it’s among the top six per cent of movements for accuracy. So wherever you are – or wherever you want to be – you’ll always be on time.

‘You shoot me down but I won’t fall, I am titanium’. It’s not often the CW Blog opens with lines from a song, let alone a 21st century chart-topper by a French DJ. But regardless of how you feel about David Guetta or his songwriting vocalist Sia, they were certainly onto something with their sentiments.

Titanium, a material with the highest strength-to-density ratio of any metallic element, was first discovered by clergyman William Gregor in Cornwall in 1791 – pretty good going for somebody who only studied geology as a hobby! – and its reputation has only blossomed since.

Lightweight yet reassuringly robust, its properties have seen it become the go-to choice for manufacturers across a range of industries. Here are just a few of its practical applications:

Whilst aluminium is used in the construction of many aircraft due to its strength and low density, its melting temperature properties simply wouldn’t suffice in the case of the Lockheed SR-71 Blackbird, a surveillance aircraft that set an absolute speed record of Mach 3.3 (2,193.2 mph; 3,529.6 km/h). Titanium was used in 85% of its structure and exterior specifically due to its higher melting point and resistance to cavitation; essential for a plane travelling at supersonic speeds, and the high levels of friction, changes in pressure and shock waves that would entail from breaking the sound barrier.

Surgical implants

As some of us may be all too aware, our bodies aren’t as reliable as we’d like! With knees and other joints wearing away over time, or the occurrence of other unfortunate injuries, science has advanced to a stage that organic parts can be replaced by synthetic ones – and this is where titanium comes in. Its remarkably biocompatible: its density is similar to that of human bone, meaning the two can readily work together, allowing its use in situations such as replacement skeletal parts, sockets and more. Just as importantly, it’s durable: these titanium substitutes can be relied upon for decades.

Sporting equipment

In sports where the weight and efficiency of equipment is key, titanium once again comes up trumps. Lighter and stronger than steel, and with high fatigue strength, it’s used commonly in racing bike frames, bobsleighs, racing wheelchairs, tennis rackets and more.

Watches

With titanium finding its way into a variety of industries, it was only a matter of time before its introduction into the world of watchmaking – namely, in 1970’s Citizen X8 Chronometer. Its inclusion makes a lot of practical sense. Many watch cases are constructed from materials such as stainless steel or bronze; the former heavy and susceptible to scratches, the latter producing its own oxidized finish over time, and both potentially capable of reacting to its wearer’s wrist. Titanium’s biocompatibility negates this possibility, while its lightness and strength makes it perfect for use in dive and sports watches.

C60 Elite 1000 watch by Christopher Ward

Nowhere is this more evident than in the new C60 Elite 1000. As a dive watch water-resistant to depths of 1000m, you might expect it to have a considerable heft; perhaps, subconsciously, this is because we associate strength with weight. The Elite 1000’s Grade 2 titanium case both silences and redefines that logic. Weighing just 77g (and 133g when worn on its new full Grade 2 titanium bracelet option) it’ll sit discreetly on the wrist – but this isn’t a watch you’ll forget about. With an exhibition caseback revealing a decorated Sellita SW220 movement, a day/date complication and Grade X1 GL C1 Super-LumiNova® adorning its bezel, hands and indexes, the C60 Elite 1000 isn’t just a beautiful diver’s watch; this new open series model can be admired (and worn) by pretty much anyone.
