On the wrist

There is something immediately disarming about the Field Automatic Gen 2: at 54g case-only, it feels almost too light to be taken seriously, and then you notice the crisp bevel lines and the depth of that sandblasted matte finish and change your mind. The dropped lugs shorten the 46.6mm lug-to-lug against the wrist so the 40mm diameter wears closer to a 38mm in perceived heft, and the 8.8mm perceived thickness means it disappears under any cuff without protest. The finish does not demand attention — it sits quiet and purposeful, the sort of watch you forget you are wearing on a long trail.

The dial splits opinion, and that is part of its character. The two-level architecture — a sunburst metal centre ringed by a sloped chapter track with recessed stencil-cut Arabic numerals filled in with Super-LumiNova — is genuinely distinctive, but it reads modern-industrial rather than vintage-military. Legibility is excellent, and the BGW09 Grade A fill is bright enough to read comfortably in a dark tent. The sapphire caseback revealing the SW200-1 in motion is a pleasant bonus at this price. Quick-release straps come off without tools in seconds, and the optional carbon deployant clasp with its 7mm micro-adjust is the most practical closure system in this segment — a detail that makes the leather-strap add-on genuinely worth considering.

Bottom line

A compelling value proposition in Swiss-made titanium at sub-$1,000 that rewards buyers who want genuine engineering and a contemporary design language over vintage-inspired military aesthetics.

Who it's for

Buyers with roughly 6.5–7.5-inch wrists who want an everyday all-terrain Swiss-made tool watch that stays featherlight in outdoor conditions. The contemporary dial design and hardened titanium case appeal to those who prioritise engineering and modern execution over heritage styling.

Who should skip it

Skip it if you want a stainless-steel bracelet option, a traditional printed-chapter-ring field-watch dial, or a case under 39mm.

FAQ

Is the Field Automatic automatic or quartz?

It runs a automatic movement.

What movement does the Field Automatic use?

The Sellita SW200-1 (Sellita).

Does the Field Automatic have a date?

Yes.

How water resistant is the Field Automatic?

It is rated to 150 m.

How big does the Field Automatic wear?

40 mm wide with a 46.6 mm lug-to-lug.

How does the Formex Field Automatic compare to the Hamilton Khaki Field Automatic?

The Formex is lighter (titanium vs steel), thinner on the wrist due to dropped lugs, and carries a more avant-garde dial; Hamilton offers vintage-military aesthetics and much wider retail availability at a comparable price. Both are Swiss Made.

What changed between Gen 1 (2022) and Gen 2 (2025)?

The Gen 2 reduces the case diameter from 41mm to 40mm, introduces a redesigned two-part sunburst dial with new color options, and drops case-only weight to 54g; the hardened titanium construction and SW200-1 movement carried over.

Is the micro-adjust carbon deployant clasp worth the extra cost?

The patented 7mm fine-adjustment system lets you resize the fit on the fly without removing the watch — practical when layering over base layers in the field. Reviewers broadly consider it a genuine functional upgrade rather than a gimmick.
