Zenith Class Elite Moonphase 18.1125.691.02.C490 specifications

For current specifications and warranty terms on Zenith's Elite line, see the manufacturer's own Fédération de l'Horlogerie Suisse industry reference and Zenith's chronometer testing background at the Contrôle Officiel Suisse des Chronomètres, the body that certifies many Swiss automatic movements including several Zenith calibres.

What does the Elite platform mean for this watch?

Elite is Zenith's line of slim, self-winding movements built for dress cases rather than sports watches, developed as an alternative to the brand's better-known El Primero chronograph family. The Class Elite collection pairs that movement architecture with classical case designs, and the Moonphase variant adds a lunar display module driven off the base calibre. The result is a genuine complication, not a simple date function, housed in a case sized for a shirt cuff rather than a diver's wetsuit.

How does the 40mm rose gold case wear?

At 40mm the case sits in a useful middle ground for a dress watch: large enough to read at a glance across a dinner table, small enough to slide under a cuff without catching. Solid rose gold adds noticeable weight compared with a steel Class Elite of the same diameter, and the warm tone reads differently in daylight than under evening light, an effect precious-metal dress watches share generally. The black leather strap is a deliberate contrast choice; a lighter strap would compete with the gold rather than frame it.

Reading the silver dial and moonphase

The dial mixes applied index markers with Arabic numerals at select hours, a layout that gives the dial texture without crowding it. The moonphase aperture sits at six o'clock, a conventional placement that keeps the disc legible without disturbing the dial's symmetry. On a well-kept example the silver surface stays bright and the printing sharp; dial condition is one of the first things to check on any pre-owned example, since moisture and handling mark silver dials more visibly than black ones.

18.1125.691.02.C490 vs a steel Class Elite: rose gold or steel?

Buyers who want a genuine complication and a precious-metal case gravitate to the rose gold moonphase; buyers who want the same design language for daily wear generally choose steel. Browse both in our Zenith collection.

Class Elite Moonphase vs El Primero: which Zenith fits you?

The Elite and El Primero families answer different briefs. El Primero is Zenith's automatic chronograph movement, first introduced in 1969 and still the basis for the brand's Chronomaster sports-oriented watches: larger cases, tachymeter bezels, a sportier stance. The Class Elite Moonphase is the quieter alternative, an ultra-thin dress movement with a calendar complication rather than a chronograph. A buyer choosing between them is usually choosing between a watch built to be worn with a suit and one built to be worn with a jacket off. Our El Primero collection covers the chronograph side of the range.

How much does a Zenith Class Elite Moonphase cost in 2026?

Precious-metal complications from established Swiss manufactures move within a wide band depending on brand, condition, box and papers, and this reference is no exception; any figure quoted without those details is only a starting point. Bizak's sourced catalogue listed this specific example, ref. 18.1125.691.02.C490 in rose gold with a silver dial, at US$22,500 on 28 September 2026, sourced to order and subject to confirmation on the day. We do not have an independent dealer-to-dealer market survey for this reference to compare against, so treat the catalogue figure as a single dated data point rather than a market median.

Ask for a dated quote against the exact case, dial and set before committing; our price-guide approach for gauging dealer quotes applies across brands, not only Rolex.

Buying a pre-owned Class Elite Moonphase: what to check

• Case condition. Rose gold marks and polishes more readily than steel. Ask for close photographs of all four case sides and the bezel edge under strong light before committing.
• Moonphase accuracy and function. Confirm when the moonphase was last set and whether it advances smoothly. A drifted display is correctable and not a dealbreaker on its own, but it is a fair question to ask before you buy.
• Dial originality. Sharp, evenly printed numerals and index markers are the baseline; blurred or misaligned dial text on a precious-metal watch is a warning sign worth investigating further.
• Serial and paperwork. Ask for the serial number and any accompanying papers, and confirm they correspond to the watch in hand rather than a similar reference.
• Service history. A documented service, or at least a clear account of the watch's history, matters more at this price point than an unverifiable claim of "recently serviced."
• Strap and buckle wear. Leather straps age faster than metal bracelets; factor a replacement into your budget if the strap shows heavy creasing or cracking.

Our authentication process describes what we check before any watch leaves the desk.

Who should buy the 18.1125.691.02.C490?

This reference suits a buyer who wants a genuine mechanical complication in a precious-metal dress case rather than a sports watch with a date window. It fits someone who attends formal events regularly and wants a watch that reads as considered rather than loud, and it appeals to a collector assembling a set of Elite-family references who specifically wants the moonphase variant over the plainer time-and-date model.

Quick answers

What is the current asking price for the Zenith Class Elite Moonphase 18.1125.691.02.C490?

Bizak's sourced catalogue listed this pre-owned example at US$22,500 on 28 September 2026, sourced to order. The figure is a dated observation, not a live quote; confirm current pricing directly before committing.

Is 40mm the right size for a rose gold dress watch?

For most wrists, yes. A 40mm case in solid gold reads clearly at a formal table and fits under a shirt cuff without forcing, a middle ground many dress-watch buyers prefer over larger sport-watch diameters.

What movement powers the moonphase complication?

An automatic movement from Zenith's Elite family, the brand's line of slim self-winding calibres built for dress cases, fitted with a moonphase module.

How is the Class Elite different from Zenith's El Primero watches?

El Primero is Zenith's automatic chronograph movement, used in the brand's sportier Chronomaster line. The Class Elite Moonphase uses a different movement family built for slim dress cases with a calendar complication rather than a chronograph.

What should I check before buying this reference pre-owned?

Case condition, moonphase accuracy, dial originality, matching serial and paperwork, and service history. Ask for current photographs of the specific watch rather than relying on catalogue images.
