The Eterna Eternity 18K Gold is a Swiss men’s chronograph that combines the restrained styling of the Eternity collection with the precision and practicality of a quartz movement. Despite the “18K Gold” wording used in the seller’s listing, the manufacturer identifies the case as stainless steel with 4N PVD gold-tone treatment rather than solid 18K gold.
At its core is the Swiss-made Ronda 5040.B quartz calibre, providing conventional timekeeping together with a chronograph capable of measuring elapsed time to 1/10th of a second. With a 42 mm diameter, 9.70 mm thickness, 22 mm lug width and approximately 48 mm lug-to-lug, this model combines contemporary proportions with the relatively slim profile expected from an elegant quartz chronograph.
Design
The Eterna Eternity 18K Gold uses a traditional round case with clean proportions and a distinctly classic two-tone appearance. The case measures 42 mm in diameter and 9.70 mm in thickness, while the approximately 48 mm lug-to-lug measurement keeps its overall footprint relatively controlled for a watch of this diameter. A 22 mm lug width provides a broad transition between the case and bracelet, helping the different components appear visually integrated.
A fixed gold-tone bezel surrounds the light silver opaline dial and establishes much of the watch’s formal character. The dial uses a balanced three-register chronograph configuration, complemented by slender applied baton hour markers and matching gold-tone hands. Fine graduations around the perimeter provide the detailed timing scale expected from a chronograph, while the 3 recessed counters add structure without overwhelming the relatively open dial. The Eterna name and characteristic 5-sphere emblem are positioned beneath 12 o’clock, maintaining the restrained presentation associated with the Eternity collection. Eterna officially describes the dial as light silver opaline.
The dial is protected by a scratch-resistant sapphire crystal with anti-reflective treatment. This reference is paired with a two-tone stainless-steel bracelet incorporating 4N PVD-treated sections and a folding clasp. Alternating steel and warm gold-tone surfaces connect the bracelet visually with the bezel, crown, pushers and dial furniture, giving the chronograph a coherent dress-oriented appearance.
Case & Construction
The case of the Eterna Eternity 18K Gold is manufactured from stainless steel with 4N PVD-treated elements and measures 42 mm across, 9.70 mm thick and approximately 48 mm from lug to lug. The 22 mm lug width is proportionate to the case diameter and gives the bracelet a substantial attachment point. The construction combines brushed and polished surfaces, creating controlled contrast between functional and decorative areas of the exterior.
Eterna specifies a snap-secured caseback, while the front of the watch is protected by an anti-reflective sapphire crystal. A conventional crown is positioned between 2 chronograph pushers on the right side of the case, allowing direct control of the timing functions. Water resistance is rated at 50 metres (5 ATM), making the watch suitable for normal everyday exposure to water rather than swimming, diving or professional aquatic use.
Movement
Inside the Eterna Eternity 18K Gold is the Ronda 5040.B, a Swiss-made analogue quartz chronograph movement produced by Ronda. Instead of storing energy mechanically in a mainspring, the calibre uses a replaceable battery to power an electronic quartz regulating system and the motors responsible for moving the hands and chronograph indications. This architecture provides the accuracy, convenient operation and comparatively low maintenance requirements associated with modern Swiss quartz watches.
The compact architecture of a quartz calibre also contributes directly to the watch’s dimensions. At only 9.70 mm thick, the complete Eternity Chronograph remains noticeably slimmer than many mechanical chronographs with a similar 42 mm diameter. The Ronda 5040.B is designed specifically for multifunction analogue chronographs and supports timing to 1/10th of a second, together with longer elapsed-time measurements. Its combination of Swiss manufacture, established industrial production and practical chronograph functionality makes it a technically appropriate choice for a watch intended to combine traditional styling with straightforward everyday ownership.
Functions & Complications
This Eterna Eternity 18K Gold provides the essential indications of hours, minutes and running seconds, together with a multi-register chronograph. The Ronda 5040.B architecture allows the chronograph to measure elapsed time to 1/10th of a second, with the additional registers providing longer timing intervals. Operation is handled through the 2 pushers positioned above and below the crown, following the conventional start, stop and reset arrangement of an analogue chronograph.
For this specific reference, Eterna’s official specification lists hour, minute, second and chronograph functions. Although some secondary listings associate the Ronda 5040.B with a date function, this model does not display a date aperture; it should therefore not be listed as a confirmed complication for this configuration.
Performance
The combination of a 42 mm diameter, approximately 48 mm lug-to-lug and 9.70 mm thickness gives the Eterna Eternity 18K Gold a relatively balanced wrist profile. Its diameter provides noticeable presence, while the short overall length and slim case reduce the bulk that is often associated with larger chronographs. The 22 mm bracelet attachment also maintains an appropriate visual proportion between the case and bracelet.
The light dial and slim gold-tone markers provide clear visual separation, while the anti-reflective sapphire crystal helps reduce reflections in changing lighting conditions. Quartz regulation makes the watch particularly convenient for frequent or occasional use because it does not require manual winding or regular wrist movement to maintain its power supply. Water resistance of 50 metres (5 ATM) is adequate for routine daily wear, although the construction is clearly oriented toward dress and general-purpose use rather than demanding aquatic activities.

The Eterna Eternity 18K Gold reflects the brand’s traditional approach to understated Swiss watch design while adopting the practicality of a modern quartz chronograph. Its 42 mm case, slim 9.70 mm profile, 48 mm lug-to-lug measurement, sapphire crystal and Ronda 5040.B movement make it particularly suitable for buyers looking for a refined chronograph that remains straightforward to own and wear.
The model’s strongest characteristics are its 1/10th-second timing capability, restrained silver dial, two-tone construction and relatively thin case. It also represents a useful example of how Eterna combines classical styling with externally supplied Swiss quartz technology. Importantly, the verified manufacturer specification describes the gold-coloured construction as 4N PVD-treated stainless steel rather than solid 18K gold, a distinction that should be maintained when identifying and evaluating of this watch.
