Isotope HydriumX "Will Return" Red & the "Wall Return" Clock

Isotope Watches introduces the new Hydrium X Will Return Red wristwatch and the Wall Return quartz clock.

Sometimes, you pass a shop window, and your eyes catch something unusual. While you press your nose against the glass, you notice the 'will return' sign, realising that you can't have what you crave, as the shop is currently closed.

In a slightly different setting, this was the experience of many watch enthusiasts when we launched our signature divers' watch, the HydriumX Will Return, inspired by this particular sign in 2021. With its white dial filled with Swiss Super-LumiNova, red hands, and a light blue bezel with a red Lacrima marker, it mimicked in a novel way the sign that so many of us see regularly in stores around the world.

As a unique concept within the world of watches, we were not prepared for its success, with the 100 pieces of this limited edition quickly selling out. The HydriumX 'Will Return' was later honoured to be selected to compete in the prestigious Grand Prix d'Horlogerie de Genève (GPHG) of 2022.

Its colourful character opened the door for more extravagant designs, not only at Isotope but also with other brands. It became a trailblazer in its own right, but as a limited edition, making more was simply not an option. However, when you put up a 'Will Return' sign, you eventually have to....return!

So, back by popular demand, and thanks to the many emails and messages we gratefully received requesting the return of the 'Will Return,' we are proud to announce the sequel to this amazing watch: the 'Will Return' Red. The hands have been reworked to be closer to the original on the door sign and match the red insert of the unidirectional, 120-click bezel. 

Fitted with a comfortable, light blue FKM strap with a microblasted buckle, it doesn't hide its family resemblance with the original 'Will Return' watch. Like its predecessor, the 'Will Return' Red also features a dial coated with Swiss Super LumiNova. It offers a bold contrast with the black Arabic numerals and minute track that make the dial so legible. It is protected by a double-domed sapphire crystal with an antireflective coating.

Like every HydriumX does also the 'Will Return' Red features a 40mm large case made from micro-blasted 316L stainless steel. The screw-down crown and case back ensure a water resistance of up to 300m/30atm/1000 feat. The Swiss-made Landeron movement can be admired through the glass insert in the case back, showcasing the oscillating weight decorated with Geneva stripes and Isotope's hallmark Lacrima. The rest of the movement pleases with a finish of circular graining, while blued screws add a dash of colour.

As good things come to those who wait, does Isotope also launch a clock mimicking the recognisable design of the original 'Will Return.' As we pride ourselves on having a sense of humour, we could not help but name this clock “Wall Return”. To ensure that your eyes continue to return to the wall when our clock is hanging there, we poured our love for details into its creation, ensuring that no detail was overlooked.

With a diameter of 35cm and featuring a singular domed crystal, the case is intricately crafted from aluminium, faithfully preserving the serrated edge characteristic of the original diving bezel. For the 'Wall Return', we broke our tradition of relying on Swiss-made movements, yet for good reason. As you have less physical contact with a clock, Isotope opted for a reliable quartz movement made in Japan. 

To still retain that mechanical vibe, it features a smooth sweeping second, which has the added advantage of being very quiet as well. The 'Wall Return' takes the colour scheme of the original 'Will Return,' including its fully luminous dial, making the clock, even in the dark, an eye-catcher.

As we hate to disappoint our fans and loyal customers but also pride ourselves on exclusivity, we decided not to make the 'Will Return' Red and 'Wall Return' a limited edition, but instead only allow ordering them in a pre-set window. From Monday, 9 am GMT, March 4th, until midnight on Sunday, March 10th, the 'Will Return' Red and 'Wall Return' can be ordered either together or separately before we turn our 'Will Return' sign once again.

After the conclusion of the limited release, the Will Return Red will no longer be available for purchase. The Wall Return will also be restricted in quantity and individually numbered, akin to the Original Release. Shipping is expected to commence in early September.

Nonetheless, the Wall Return will continue in our offerings, albeit without the numbered case of a special edition, and will be priced at a higher cost per unit.
