The Spinnaker Dumas GMT is an exciting addition to the Spinnaker lineup, blending vintage aesthetics with modern functionality. Let’s dive into what makes this watch special and why it might be the perfect addition to your collection.

Introduction

When it comes to affordable dive watches with a GMT function, the Spinnaker Dumas GMT truly stands out. Inspired by famed dive pioneer Frederic Dumas, this watch combines a robust design with practical features. Whether you’re an avid collector or someone looking for a reliable watch for your adventures, the Dumas GMT has a lot to offer.

Design and Build Quality

The Dumas is definitely a striking-looking watch! It reminds me, in some ways, of the Omega Proprof with its sword-style hands and chunky, strong case style. Obviously, though, the Spinnaker is a far more affordable and attainable watch! The 70s-inspired octagonal case measures 44mm in diameter and 15mm in thickness. It’s made from quality 316L stainless steel, which is known for its durability and corrosion resistance. The scratch-resistant sapphire crystal with an anti-reflective coating ensures maximum legibility and durability.

The overall design is bold yet comfortable, delivering an impressive 300m of water resistance. This makes it perfect not only for diving but also for any tough environments you might find yourself in.

Movement and Functionality

One of the standout features of the Spinnaker Dumas GMT is its movement. The watch uses the reliable Seiko TMI NH34 GMT Japanese Automatic movement. This choice of movement is always a pro as it makes servicing and reliability less of a concern in the long term. Plus, the added GMT functionality will no doubt appeal to a lot of people, allowing you to track multiple time zones effortlessly.

The bi-directional bezel with hardened glass not only adds to the watch's rugged appeal but also provides functionality. It allows you to keep track of a third-time zone, which is great for frequent travellers.

Dial and Legibility

The dial of the Dumas GMT is a masterclass in legibility. With big markers and Swiss Super-LumiNova, visibility is excellent both day and night. The use of large, distinct hands makes it easy to read the time at a glance. The dial also features a date window at the 3 o'clock position, which is a practical addition for everyday use.

Straps and Comfort

Comfort is key with the Spinnaker Dumas GMT. The watch hugs the wrist thanks to a solid, yet comfortable hexad style bracelet. It also comes equipped with a uniquely customized rubber strap designed to complement each unique colorway for added versatility and wear options. I always appreciate when manufacturers include an additional strap. Extra options straight out of the box are great to see and provide versatility in styling.

Size and Wearability

Now, the Dumas is not a small watch, and that 44mm size may be a bit large for some people’s wrists. However, thanks to the case shape with those very short downturned integrated lugs, it may well wear better than you expect. There’s no doubt this is a big, chunky watch, but if you like that style, it's hard to argue with what Spinnaker has done with the Dumas.

The Spinnaker Dumas GMT is priced at $550 (USD) and £570 (GBP).
