Quick take: The ARISTO RLM-Uhr 7H110A-RLM is a modern, Germany-made riff on a 1940s “service watch” look: a clean black dial with big Arabic numerals, a small seconds subdial at 6, and a no-date Sellita automatic inside. If you like vintage military legibility but want modern sapphire and a mainstream Swiss movement, it’s worth a look.

What it is (and why it works as a field watch)
Field watches are basically legibility-first everyday tool watches: clear numerals, no nonsense, comfortable sizing, and enough durability for real life. The RLM-Uhr leans into that with a high-contrast dial, straightforward handset, and no date window to clutter the layout.
If you’re new to the category, start here: What is a field watch? Then use the 10-point checklist to sanity-check any watch before you buy.
Size & wear
At 38.5mm, the RLM-Uhr sits in a “safe” modern field-watch zone: big enough for quick reads, but not so large that it turns into a cockpit-watch cosplay piece. If you’re deciding between the classic field sizes, this guide helps: Field watch size guide.
Dial, legibility & lume
This is the core of the watch: 12 big Arabic numerals, a railroad-style minute track feel, and a small seconds display at 6 that adds vintage flavor without hurting readability.
Lume is listed on the numerals and hands. Expect it to be useful for “find the time after lights-out” more than “torch replacement.” (If you want a deeper lume deep-dive, we have a guide in draft, but the practical short version is: application + surface area matter more than buzzwords.)
Movement notes (Sellita SW200-1)
The SW200-1 is one of the most common Swiss automatic movements in “serious but not crazy-money” watches. It’s easy to service in most places, and ownership is straightforward. If you’re comparing movement types (quartz vs automatic vs manual vs solar), this explainer helps: Field watch movements.
Water resistance & durability reality check
ARISTO lists 5 ATM water resistance. In practical terms: fine for rain, handwashing, and daily wear; not the spec you pick for regular swimming. If you want the nuance behind the numbers, read: Water resistance explained.
Buying notes (variants to watch for)
- ARISTO also lists a manual-wind version in the same family (7H110H-RLM). If you prefer thinner cases and the daily wind ritual, it may be worth comparing.
- Confirm strap length if you have a small/large wrist—leather straps vary a lot.
- If you’re picky about lume performance, look for real-world owner photos/videos (not just studio shots).
Alternatives (different vibes, same “field-first” intent)
- Hamilton Khaki Field Mechanical 38mm (manual-wind, classic modern benchmark)
- Bulova Hack Watch (field-watch DNA with a different case/dial feel)
- Seiko 5 Sports Field SRPG27 (automatic value pick)
- Vaer C3 Korean Field (Solar, 36mm) (low-maintenance, smaller, very practical)
Who it’s for
- You want a vintage military/service-watch look without going full “reissue cosplay.”
- You prefer no-date symmetry and a classic subseconds layout.
- You want a serviceable Swiss automatic in a compact case size.

Verdict
The ARISTO RLM-Uhr 7H110A-RLM is a niche pick in the best way: it’s not trying to be everything, it’s trying to be easy to read and easy to live with. If you like subseconds dials and the clean, high-contrast service-watch vibe, it’s a compelling alternative to the more common Hamilton/Seiko choices.
