Its 38.3 mm case, 200 m water resistance and independently settable 24-hour hand make it a practical two-time-zone watch—but it is not a Pepsi-bezel substitute in the literal sense: Vulcain’s product pages describe a ceramic bezel without documenting the classic red-and-blue color scheme.
What makes the Skindiver Nautique GMT different?
Vulcain positions the watch as a modern extension of its 1960s Skindiver heritage, adding a second time zone. The brand puts the distinction plainly: “This is not a reissue.” Vulcain’s launch page frames it as a heritage-inspired design rather than a reproduction of a specific vintage reference.

The result is a diver-shaped GMT with relatively restrained dimensions. Vulcain lists a 38.3 mm case diameter and 12.2 mm thickness, plus a double-domed sapphire crystal and 200 m water resistance. Those specifications suit someone who wants a capable sports watch without the larger case dimensions common to many contemporary divers.

#1 Best Overall
- 【Premium Automatic GMT Watch】Built around the reliable NH34 self-winding mechanical movement, this 43mm dive watch features an independent 24-hour GMT hand for dual-timezone tracking, 41-hour power reserve, and daily accuracy of -20 to +40 seconds. The dial is finished with a striking sunburst texture and a 3D logo at the 12 o'clock position, elevating the luxury feel.
- 【300M Professional Dive-Ready Build】Crafted from corrosion-resistant 316L stainless steel, this watch is built for underwater performance. It features a scratch-resistant unidirectional rotating ceramic bezel, a screw-down crown, and a screw-on exhibition caseback with sapphire crystal. With a 30ATM water resistance rating, it stands up to swimming, snorkeling, and professional diving activities.
- 【High-Visibility BGW9 Super Luminous】Legibility is key in low-light conditions. The hands, hour markers, and bezel are all infused with Swiss-grade BGW9 Super-LumiNova (not just coated), emitting a bright, pure blue glow after brief light exposure. This ensures over 90% night-time readability, so you can check the time clearly even in complete darkness.

The bracelet is made of solid 316L stainless steel, fitted with a secure dual-push dive extension clasp for a comfortable fit over wetsuits (3-7mm thick). It also includes a quick-release premium silicone strap for easy swaps between sporty and casual looks.

Is it actually a Pepsi GMT alternative?
Only in the broad sense that it is a GMT watch. “Pepsi” usually refers to a red-and-blue bezel, but the Vulcain product material reviewed here specifies a bidirectional ceramic bezel and does not establish that color combination. Another Skindiver GMT listing also describes a ceramic bezel. Vulcain’s Black Luminova Beige listing is one example.
That means the comparison is about the kind of watch you want, not a direct specification match with an unnamed rival. A meaningful head-to-head would require a specific Pepsi GMT reference: case size, thickness, bezel color and rotation, GMT-hand setting method, movement, reserve, water resistance, price and availability all vary by model. The available Vulcain listings establish its side of that comparison, but not which competing reference the headline has in mind.

Which versions are listed, and what is known about availability?
Vulcain’s collection page presents GMT Blue and GMT White variants and describes the line as a two-time-zone Skindiver. The Skindiver collection page is the manufacturer’s current variant reference. Timekeepers Club recorded an announcement of white and limited blue variants in September 2025; that dated report provides launch context, not confirmation of current inventory. Timekeepers Club’s Vulcain brand page does not establish live stock or pricing.

Who is this watch for?
- Consider it if you want a smaller-case diver with 200 m water resistance and a mechanically set second time zone.
- Consider it if you like vintage-inspired styling but prefer a contemporary watch rather than a strict reissue.
- Look elsewhere if your priority is specifically a red-and-blue Pepsi bezel; Vulcain’s reviewed product descriptions do not document one.
- Compare exact references before buying if you are choosing between this and another GMT diver, since shared GMT functionality does not make their movements, bezel behavior or dimensions equivalent.
