- Single-domed sapphire crystal with AR coating
- 100m WR + screw-down crown
- W20 SuperLuminova
- A-11-inspired field design
Who it's for
Buyers who want a versatile, no-nonsense automatic field watch sized for everyday use: the 40mm case and 48mm lug-to-lug fit average to slightly large wrists equally well. The strap-swap ecosystem (rubber, nylon, leather, steel bracelet all available) makes it at home at a desk or on a trail, and the 100m water resistance means it never needs to come off for the gym or beach.
Who should skip it
Skip it if a clean no-date dial is non-negotiable, if you want a genuinely slim dress-field profile under 10mm, or if you need a case larger than 40mm.
Before you buy

FAQ
Is the A5 Field automatic or quartz?
The A5 Field is automatic. The Miyota 9015 winds itself from the motion of your wrist, so it needs no battery. A full wind holds roughly 42 hours, so it keeps running overnight off the wrist; left longer it stops and restarts once you wear or hand-wind it.
What movement does the A5 Field use?
The A5 Field is powered by the Miyota 9015 from Miyota, an automatic caliber with 24 jewels, a 42-hour power reserve, and a 28,800 bph beat rate. Being automatic, it winds from the motion of your wrist and needs no battery.
Does the A5 Field have a date?
Yes — the A5 Field has a date display on the dial. The date advances automatically as the movement runs, so the current day of the month is always visible at a glance, and you can set it from the crown after the watch has been left to stop.
How water resistant is the A5 Field?
The A5 Field is rated to 100 m. That covers swimming and snorkelling, though hot water and direct high-pressure water are best avoided, and it is not intended for scuba diving. Whatever the rating, avoid operating the crown or pushers underwater, and have the gaskets checked periodically to keep it reliable.
How big does the A5 Field wear?
At 40 mm across with a 48 mm lug-to-lug and 10.4 mm thick, the A5 Field wears as a modern medium-to-large watch. Lug-to-lug is the measurement that really decides fit, since it sets how far the case spans the wrist — 48 mm suits most wrists, and smaller wrists especially should check that figure.
How does the A5 Field compare to the Hamilton Khaki Field Auto?
The A5 undercuts the Hamilton Khaki Field Auto by about $196-$246, matches it on sapphire crystal and 100m water resistance, and adds a screw-down crown; the Hamilton counters with stronger brand heritage, a wider model range, and no-date options elsewhere in the Khaki Field range such as the Mechanical or Murph.
What does 'USA assembled' actually mean?
Vaer's US assembly teams handle final casing, regulation, timing, and waterproof pressure-testing; the Miyota 9015 movement and components are sourced from Japan. It is not a Swiss-made or fully domestically manufactured piece.
Is a no-date version of the A5 Field available?
No — all current A5 Field variants include the date window at 3 o'clock. Buyers who prefer a cleaner dial should note this before purchasing.
