You might remember my review of the Hydrium in which I commented on the collecting opportunity offered by this watch from British based brand Isotope. Well now two more have joined the line-up, the Hydrium Pro Nordblad and the Hydrium Nasa.

Hydrium Pro Nordblad

This is the second watch from Isotope developed as a tribute to the achievements of Johanna Nordblad, a the world-renowned ice diver. LIke the previous “Goutte d’Eau version this watch features a blue second hand. Limited to 100 pieces, it is the first of a series of Hydrium Pro watches, exceeding specifications above ISO 6425, the official divers watch certification . The watch case is made of sandblasted 316L stainless steel. All the crystals, including the bezel, are made of sapphire crystal and the movement is a top-finished and regulated Swiss Landeron. If any of these watches remain unsold they are offered at £900 (ex VAT) on the Isotope website

Hydrium NASA

As well as Hydrium collectors, this second officially NASA approved watch, launched on April 15th, should appeal to the many space fans out there.

Apart from the special NASA nato strap what makes this watch stand out is the polymer-ceramic coating, Cerakota that has been applied to the 316L steel case. This coating replicates the texture of the re-entry capsule’s vitally important heat shield. Then there is the NASA logo above the six o’clock position.

This watch is also available from the Isotope website for £825 (ex VAT) includedin this price is an extra grey quick release FKM strap

This watch is limited to 200 pieces, and available to pre-order through www.isotopewatches.com with expected delivery starting in August 2023. Currently priced at £825 (ex VAT) which includes a second grey quick release FKM strap.
