LE MANUEL 002 / WRIST & FIELD INSTRUMENTS
Pour la collection : montres soviétiques, militaires françaises, et instruments de terrain.
Manual metadata
This manual establishes a working taxonomy for wrist-worn and portable field instruments inside Forgotten Industries. It is not a buying guide and not yet a dossier. It is a reference plate: a compact instrument used to compare cases, track acquisitions, preserve observed examples, and identify adjacent objects worthy of future archive records.
What belongs on the wrist, in the pocket, or in the field bag of an archive built against forgetting?
01 / Case Architecture
| Case | L2L | Diameter | Verdict | Notes |
|---|---|---|---|---|
| 710 · Ministry | ~45mm | ~41mm | Best balance | Cushion shape, tapered profile, and enough presence for the wrist without losing comfort. |
| 170 | ~46mm | ~42mm | Strong | Large on paper and on wrist; a useful bridge between the 710 and 090 families. |
| 090 · Tonneau | — | ~42mm | Strong | Rectangular tonneau shape adds visual heft beyond the diameter figure. |
| 120 | ~49mm | ~40mm | Biggest L2L | Tall relative to width; can read clunky despite the useful lug-to-lug number. |
| 100 | — | 40mm | Solid | 12mm thick with 18mm lugs. Comfortable middle ground. |
| 420 | — | ~40mm | Runs small | Short lugs and no crown guards. Same dial options, less wrist presence. |
| 110 | — | — | Skip | Lugs do not curve down; rides high and does not suit the working target. |
| Komandirskie standard | ~37-40mm | 37-38mm | Dress size | 30m water resistance only. Prefer Komandirskie 200m / 43-case crossover examples. |
02 / Collection Roster
First Soviet watch. Biggest case in the collection, confirmed by spec sheet rather than estimate.
Reference pick, not yet bought. Clean specification, trusted seller, no import gamble.
Research-scientist aesthetic. Matches two decades of 24-hour time fluency.
Modern reliability bridge between Soviet pieces and serious complications.
02.1 / Spotted in the Wild
FI-WATCH-OBS
Auto movement, rubber strap, blue sunburst dial, "Восток" branding, and dotted bezel insert in matching blue. Reference example of the cushion-case diver family in a colorway not yet covered by the roster.
Future comparison target against the 710/170 case notes in Section 01.
03 / Adjacent Field Instruments
Soviet Army wrist/pocket compass with mil-graduated dial, Bakelite or metal housing, and natural wrist pairing with a Vostok.
Adrianov sibling with hinged mirror cover for simultaneous orientation and angle reading. Mils, not degrees.
Manual wind-speed meter from the same material era as the watch collection. Working examples remain obtainable.
Bamboo-bodied Japanese pocket slide rule. Engineer/scientist kit before calculators; genuinely portable field instrument.
Caliber suffix 23/24 marks the rare 24-hour Molnija variant. Long-term rarity hunt.
French Air Force flyback chronograph specification. Vintage examples are collector tier; modern reissues remain aspirational reference points.
Notes on this Manual
This manual was compiled from a single extended research session in June 2026. It converts the concept PDF into a public, maintainable reference page while preserving the PDF as a source artifact.
Case sizing guidance is calibrated to Matthew's larger wrist and 6'4" frame. Lug-to-lug and presence notes should not be generalized to smaller wrists without fresh measurement.
D'en haut, les choses se souviennent les unes des autres.
From above, things remember one another.
