The Isotope Hydrium NASA Limited Edition Watch 6HSSN24 is a unique timepiece inspired by the heat shield of NASA's reentry capsules. This limited edition watch features a 316L stainless steel case coated with a polymer-ceramic called Cerakote®, which gives each case a distinctive distressed texture, ensuring that every piece is one-of-a-kind.


The dark blue dial, adorned with Isotope's signature box-shaped hands and a central Lacrima logo, is designed for clarity and depth. The dial’s outer ring includes a railroad track for easy reading of minutes and seconds, which is practical for precise timekeeping. The red second hand complements the NASA logo at the six o'clock position, marking the official endorsement by NASA. A 120-click bezel with minute/seconds markings, along with full lume, ensures visibility in low-light conditions, from space missions to nighttime adventures. Super-LumiNova is applied to the hands and dial for enhanced legibility.


Built as a diving watch, the Hydrium NASA boasts a 300m water resistance, making it suitable for ocean splashes post-reentry. It features a double-domed sapphire crystal with an anti-reflective coating, and a screw-down crown for added security. The watch is powered by a Swiss-made Landeron automatic movement, visible through the screw-down exhibition back. This movement runs at 4 Hz (28,800 VpH) and offers a 40-hour power reserve. It is beautifully decorated with blued screws, perlage, Côtes de Genève, and the Isotope Lacrima on the oscillating weight.


For an additional touch of exclusivity, the watch comes with a strap designed by Nick Mankey Designs featuring the NASA logo. This strap ensures the Hydrium NASA stays securely on your wrist, whether during space flight or everyday activities. Available now at MVS Watches in excellent preowned condition with free UK shipping.
