This bespoke edition of the Jarvis – Blackout has been created exclusively for members of Alpha Diving Unit. Each piece features an engraved caseback and unit dial print. The dial carries the clean, utilitarian aesthetic of the standard Jarvis but with subtle, unit-specific detailing unique to this collaboration. The tip of the GMT hand has been matched to the units blue colour within its logo. Each watch will come shipped on the rubber strap, and have a spare black zulu strap. Watches will be produced and assembled once the order window closes, with delivery estimated at 3–5 months from that point. Please note: due to the use of a screw-down caseback, engraving orientation cannot be guaranteed.
