Raymond Weil · Freelancer · Ref. Freelancer RW1212

Most Raymond Weil references carry Sellita or ETA-family movements and are correct doing so. The RW1212 is the exception rather than the rule, and treating an outside movement in an ordinary Freelancer as a finding would be wrong — the brand does not claim otherwise. Note also that the RW1212 itself was developed with Sellita rather than conceived alone, so the line between it and the bought-in calibers is one of exclusivity rather than of origin.

TSIKOLIA · Seven Automatic · Ref. TW7A-46-1GN-R

The Seven Automatic runs the Swiss ETA 2824-2 decorated with perlage, brushed finishes and a bespoke Tsikolia rotor. A plain rotor, or a Miyota/Ronda caliber where an ETA 2824-2 is expected, is inconsistent with this reference.

Hamilton · Ventura · Ref. H24411732

This is an ordinary, widely used Swiss quartz movement, marked as such. Hamilton does not claim otherwise. An examiner should expect ETA markings rather than a Hamilton in-house designation, and their presence is confirmation rather than a finding.

Laurent Ferrier · Classic Micro-Rotor · Ref. Classic Micro-Rotor

At this level hand finishing is the specification rather than a bonus. The distinguishing evidence is geometric: a rotating tool rounds off internal angles and produces bevels of uniform width, while hand work can bring an internal corner to a sharp point and varies slightly along its length. Look at the internal angles of the bridges. This is the same test the catalog applies to Montblanc's Villeret calibers.

Greubel Forsey · Double Tourbillon 30° · Ref. Double Tourbillon 30°

At this level the finishing is the product. The diagnostic is geometric rather than aesthetic: a rotating tool cannot reach into a sharp internal angle, so machine bevels round off at internal corners and hold a uniform width, while hand-applied bevels reach a crisp point and vary slightly along their length. Black polish — a flat surface reflecting either pure black or pure white depending on angle — is likewise a hand process with no machine equivalent. Examine the internal angles of the bridges and the tourbillon cage.

Vostok · Komandirskie · Ref. Soviet MoD issue

Vintage Komandirskie run the manual 2409 (17j, no date) or 2414A (17j, date), 19,800 vph. The caliber number is engraved on genuine movements; a non-Vostok movement or wrong jewel count is a red flag.

Hamilton · Intra-Matic · Ref. H38416711

The H designation is a Hamilton label, not a claim of in-house origin. Expect 7753 architecture: cam-switched chronograph, oscillating-pinion clutch, unidirectional rotor with the characteristic slight wobble, and a 60-hour reserve obtained from a revised barrel. A movement that does not present 7750-family architecture is not an H-31, whatever the rotor says.

Hermès · Arceau · Ref. Arceau (H1837 automatic)

Where the reference has a display back, expect a properly finished Swiss manufacture movement with a double barrel, a Hermès-signed rotor and 28,800 vph. This is not a decorated generic ébauche and it does not resemble one. A watch presented as an H1837 Arceau showing a plain ETA-family movement, or a quartz module, is not what it claims.

Seiko · Turtle · Ref. 6306-7001

Pull the crown to the time-setting position. The 6306A stops the seconds hand; the 6309A does not. Combined with the Kanji day wheel, this is a decisive, non-invasive check — and it is the check that catches the common misrepresentation, which is an export 6309 sold as the rarer JDM 6306.

Montblanc · 1858 · Ref. 1858 Monopusher Chronograph (Minerva)

Machine-applied bevels are uniform in width and meet at rounded internal angles; hand-applied bevels vary slightly and can be brought to a sharp internal corner, which a machine cannot do. On a caliber priced where these are, hand finishing is the specification, and its absence is a finding. This is the one place in the Montblanc catalog where finishing quality is evidence rather than aesthetics.

A. Lange & Söhne · Lange 1 · Ref. 101.021

Every Lange balance cock is hand-engraved by a single engraver, so no two are identical. A stamped or CNC-uniform cock is a clear counterfeit indicator.

A. Lange & Söhne · Lange 1 · Ref. 191.032

Every Lange balance cock is hand-engraved by a single engraver, so no two are identical. A stamped or CNC-uniform cock is a clear counterfeit indicator.

A. Lange & Söhne · Datograph Up/Down · Ref. 403.035

Expect a column wheel, hand-engraved balance cock, black-polished steel and a precisely-jumping (not creeping) chronograph minute hand. Rough finishing or a smart-creeping counter is inconsistent.

Patek Philippe · Nautilus · Ref. 5711/1A-010

Expect Geneva striping, chamfered bridges and a gold rotor visible through the sapphire back; rough finishing or an ETA-style movement is disqualifying.

Patek Philippe · Nautilus · Ref. 5811/1G-001

Expect Geneva striping, chamfered bridges and a gold rotor visible through the sapphire back; rough finishing or an ETA-style movement is disqualifying.

Patek Philippe · Aquanaut · Ref. 5065A

Expect Geneva striping, chamfered bridges and a gold rotor visible through the sapphire back; rough finishing or an ETA-style movement is disqualifying.

Patek Philippe · Nautilus · Ref. 3700/1A

Expect Geneva striping, chamfered bridges and a gold rotor visible through the sapphire back; rough finishing or an ETA-style movement is disqualifying.

Tudor · Black Bay · Ref. 79230N

The 79230 runs the COSC MT5602 with a ~70-hour reserve; the earlier 79220 uses an ETA 2824. Movement identifies the generation.

Bulova · Accutron · Ref. Accutron 214

Hold the watch to your ear: a running Accutron produces a continuous high tone at 360 Hz, not a tick. Watch the seconds hand: it moves genuinely continuously, with no increments at all. Neither behaviour can be produced by a mechanical movement, which steps at its beat rate, or by a standard quartz, which steps once a second. This is as close to a conclusive single test as this catalog contains, because it follows from how the movement works rather than from how it looks.

Jaeger-LeCoultre · Reverso Tribute · Ref. Q3978480

Reverso movements are JLC in-house (e.g. cal 822 hand-wound). A generic ETA in a Reverso is inconsistent with the reference.

Jaeger-LeCoultre · Reverso Classic · Ref. Q2548440

Reverso movements are JLC in-house (e.g. cal 822 hand-wound). A generic ETA in a Reverso is inconsistent with the reference.

TSIKOLIA · Marina Diver · Ref. TWM-42-3GN

The Marina Diver runs the 24-jewel Japanese Miyota 9015 automatic (28,800 vph, ~42h). It is finished with a custom Tsikolia rotor visible through the sapphire exhibition caseback — a non-standard or plain rotor is a red flag.

TSIKOLIA · Ori · Ref. TW2-1WT-M

The Ori runs the 24-jewel Miyota 9015 automatic finished with a custom Tsikolia engraved rotor (as on the Marina Diver). A plain rotor, or a quartz/other caliber in a purported Ori, is inconsistent with this model.

Arnold & Son · Perpetual Moon · Ref. Perpetual Moon

A standard moonphase uses a 59-tooth wheel and drifts about a day every two and a half years. A high-precision one uses a much larger tooth count to approximate the synodic month more closely, and the accuracy claimed follows arithmetically from that count. It is one of the few specification claims in this catalog that can in principle be verified by counting teeth through a display back — laborious, and conclusive.

H. Moser & Cie. · Pioneer · Ref. Pioneer Centre Seconds

Precision Engineering AG, Moser's sister company, manufactures hairsprings — something only a handful of firms in the world do. It is a genuine technical claim rather than a marketing one, and it belongs in an authentication record because it distinguishes this manufacturer from the far larger number that buy their regulating organs in.

Tissot · Astrolon / IDEA 2001 · Ref. IDEA 2001

Everything an examiner is trained to read as cheapness — polymer plates, moulding flash, a solitary jewel, no decoration — is the specification of this caliber. There is nothing to compare it against elsewhere in the catalog. The check is the opposite of the usual one: a Tissot presented as an IDEA 2001 containing a conventional metal movement is the wrong watch.

Hamilton · Khaki Field · Ref. H69439931

Hamilton's own specification and several retailers state 17 jewels — the count of the ETA 2801-2 base — while other published specifications for the same reference state 25. The catalog does not assert a figure. Do not treat a jewel count on the movement bridge as confirming or disconfirming this reference until the discrepancy is resolved against a Hamilton technical document.

Rado · DiaStar Original · Ref. R12161653

Rado's R-prefixed caliber numbers are Rado designations for ETA movements; the R764 is the C07 family with a day-date. The slow beat and 80-hour reserve are the same signature as Tissot's Powermatic 80 and Hamilton's H-10, and are factory-correct.

TSIKOLIA · P-47 Thunderbolt Chronograph · Ref. TWP47-47-2OG-LN

The Thunderbolt uses the Ronda 5040.D (Swiss quartz chronograph, 1/10s timing, ~54-month battery) — distinct from the Seven chronograph's Ronda 5040.B. A mechanical movement or a different caliber is inconsistent with this reference.

TSIKOLIA · UNIQ P-47 Thunderbolt · Ref. UNIQ P-47 Thunderbolt

Runs the Ronda 5040.D Swiss quartz chronograph, as does the modern TSIKOLIA Thunderbolt. A mechanical or non-5040 movement is inconsistent with this reference.

TSIKOLIA · Seven 40 · Ref. TW7-40G-3ROM-M

The 40mm unisex Seven uses the Ronda 5040E Swiss quartz chronograph — a different 5040-series caliber from the 46mm TW-7 (Ronda 5040.B). A three-hand movement in a purported 40mm Seven chronograph is inconsistent with this model.

TSIKOLIA · GDF (Georgian Defence Forces) · Ref. TWGDF-44-1WT-RN

The GDF runs the three-hand Ronda 515 Swiss quartz. A different caliber for a purported GDF is a red flag.

TSIKOLIA · Seven 36 · Ref. TW7-36G-3WTM-M

The 36mm Seven uses the three-hand Ronda 6003B Swiss quartz — distinct from the chronograph Sevens (46mm TW-7 on Ronda 5040.B, 40mm on Ronda 5040E). A chronograph movement in a purported 36mm Seven is inconsistent with this model.

Baume & Mercier · Clifton · Ref. Clifton Baumatic

The caliber uses silicon in its escapement and is specified for high magnetic resistance. Silicon parts are visually distinguishable from steel under magnification — different colour, different surface — and are not something a substituted generic movement will have.

Mido · Multifort · Ref. Multifort (modern Caliber 80)

As across the whole C07 family, the balance is deliberately slowed to 21,600 vph to obtain the extended reserve. A Mido Caliber 80 running at 28,800 is not carrying the caliber claimed for it, and one running at 21,600 is behaving exactly as specified.

TSIKOLIA · Seven Chronograph · Ref. TW-7

The Seven chronograph uses the Ronda 5040.B (Swiss quartz, small-seconds + chronograph). A mechanical movement or a different quartz caliber in a purported Seven chronograph is a red flag.

Certina · DS Concept · Ref. DS Powermatic 80

Six beats per second and an 80-hour reserve are correct. A Certina Powermatic 80 running at 28,800 vph is not carrying the caliber claimed for it. Where the reference has a display back, the C07's single broad bridge is directly recognisable.
