Six watches, four calibers.
An ETA, a 7S26, a 4R36, and an Omega 861. Two Pepsi divers, a vintage Submariner homage, a Speedmaster, a Seiko 5, and a Samurai. From the author’s own collection.
Swiss-made dive watch · 2010s
Steinhart Ocean One Vintage
A 42 mm homage to the vintage Submariner — domed sapphire, gilt indices, Swiss ETA automatic underneath.
ISO 6425 dive watch · 1996–2019
Seiko SKX007
The reference everyone learns mechanical diving on. Bulletproof Seiko 7S26 inside, ISO 6425 dive certification, the matte-black dial that launched a thousand mods.
Seiko 5 series · automatic
Seiko 7S26-0200
A Seiko 5 wearing the 7S26 caliber under reference 7S26-0200 — three hands, day and date, automatic, see-through caseback. The pure form of a workhorse.
The Moonwatch · pre-moon 1970
Omega Speedmaster Professional
A 1970 Speedmaster Professional, "pre-Moon" by the trade convention that the dot above the 90 on the tachymeter bezel is no longer present. The caliber 861 inside is the workhorse of every Apollo mission.
ISO 6425 Pepsi diver · 1996–2019
Seiko SKX009
The SKX007's "Pepsi" sibling — same case, same 7S26, blue-and-red bezel insert. The most-modded diver in history in its most-collected colourway.
Prospex diver · special edition
Seiko Samurai PADI
The "Samurai" Prospex with the PADI colour story — angular case, ISO 6425 dive rating, the 4R36 caliber that finally gave Seiko divers hand-winding and hacking.
