Depthmaster Black Pumpkin, a 39 mm dive watch with an orange full-lume dial, limited to 70 pieces
The Depthmaster Black Pumpkin is a 39 mm cushion-shaped dive watch with a black case, a dark orange full-lume dial and a Swiss Soprod P024 automatic movement, water resistant to 1,000 m. Nivada Grenchen made it as a limited edition of 70 pieces, and it now has its place in the Retrospective of our limited editions.
The whole dial is made of luminous material: a dark orange full-lume surface that glows in low light, not just the hands and markers. On top sit bold printed markers with a thick C3 black outline, and a printed 12 numeral.
The hour markers carry the shapes that earned the Depthmaster its "Pac-Man" nickname, a nod to the arcade game character and a detail that sets it apart from other dive watches. Discover the full family in our Depthmaster collection.
The Black Pumpkin is water resistant to 100 ATM, or 1,000 m. Its screw-down crown keeps water out, and an automatic helium escape valve makes it ready for saturation diving. A flat sapphire crystal covers the dial.
The unidirectional bezel turns in 120 clicks and carries a 15-minute scale for timing a dive. New to dive watches? Read our dive watch essentials and our guide to Swiss dive watches.

The Depthmaster takes its inspiration from the original model released in the mid-1960s, and keeps its cushion-shaped case. In 316L stainless steel, it measures 39 mm across, 47 mm from lug to lug and 13 mm thick, with 20 mm lugs. On the Black Pumpkin, the case is black, to frame the orange dial.
Inside is the Swiss Soprod P024, a self-winding mechanical movement with 25 jewels, beating at 28,800 vibrations per hour (4 Hz) with a power reserve of about 38 hours. It drives the hours, minutes and central seconds, with no date.
FAQs
Before you dive, turn the bezel until its triangle lines up with the minute hand. As time passes, the minute hand moves along the bezel scale and shows how many minutes have gone by. On the Depthmaster Black Pumpkin, the bezel turns in 120 clicks and has a 15-minute scale.
The rotating bezel lets a diver time a dive at a glance, without a stopwatch. On a dive watch like the Depthmaster, it turns in one direction only, so an accidental knock can only show more elapsed time, never less.
A helium escape valve lets helium out of the case during the decompression phase of saturation diving, so the pressure inside does not damage the watch. The Depthmaster Black Pumpkin has an automatic helium escape valve and is water resistant to 1,000 m.
