Serica 8315 Golden Green, travel told in colour

On 5 November 2026, Serica unveiled a bezel the colour of late afternoon. Its Travel Chronometer, the Ref. 8315, had already taken on the warm tones of Sand Red in 2023, a brown ceramic with red and orange accents. The Ref. 8315-3 moves it into the light, with a ceramic named Golden Green, after the golden hour. Beneath the new colour, the watch remains the instrument the house has been refining for four years, and that is what deserves a close look.

A name from the edge of the map

Before it was a brand, Serica was a region. The Greeks and Romans gave the name to the land of the Seres, whom Pliny the Elder described as famous for their silk, and fifteenth-century sea charts still drew it at the far end of the Far East. It was in front of one of those portolan charts, held by the Austrian National Library in Vienna, that Jérôme Burgert had something close to a revelation. At the time, he was looking for a name with his partners, and it is the one carried since 2019 by the house he founded in Paris with Gabriel Vachette.

The sound and the look of the word Serica appealed to me straight away. And it evokes values we stand for: those of fine mechanical pieces ready to follow us to the ends of the earth.

The Ref. 8315, launched in 2022 as the house’s vision of the GMT watch, bears the name Travel Chronometer.

A GMT that slips under a cuff

The 316L steel case measures 39 mm across and 12.30 mm thick including the crystal, with 46.5 mm lug to lug and a 20 mm lug width, dimensions the house knows well, since its diver shares them. On paper, this is a GMT water-resistant to 20 bar that keeps the proportions of an everyday watch, closer to a shirt cuff than to a dive vest.

The case alternates polished and brushed surfaces, with lyre lugs. The crystal is a 2 mm double-domed sapphire with anti-reflective coating on the inside. On the back, a solid screw-down caseback is engraved Montres Serica, Fab. Suisse, Chronomètre and 200 m / 660 ft, and can take a personal engraving, which suits a watch the house wants to carry memories. The 8 mm screw-down crown is meant to be easy to grip for winding and setting, and can sit at three or at nine o’clock. On a GMT, which gets handled more often than most watches, that is no small detail.

Two time zones, one crown

The 8315 reinterprets the traditional two-tone 24-hour bezel. The scale is split into two twelve-hour segments, with a.m./p.m. markers and a day/night indicator. The two colours are not shared out evenly, as the house wanted the day to look longer than the night. It is a choice of legibility over symmetry, and it turns the bezel into a piece of information in its own right. The hour hand is a broad arrow and the GMT hand a lollipop, both white lacquered, the round tip of the latter in orange, and the dial does without a date.

The movement is a Soprod C125, self-winding in both directions, running at 4 Hz with a 42-hour power reserve. Its Côtes de Genève decoration stays hidden behind the solid caseback. The crown has three positions: the first winds the mainspring, the second sets the GMT hand on its own, clockwise, and the third stops the seconds hand for time setting. This is what is known as a “caller” GMT. When travelling, changing local time therefore means going to the third position, with the seconds hand stopped while you set it. The bidirectional bezel offers another route, since Serica also presents it as a way to show a second time zone without touching the hands. The 8315 thus keeps a reference time zone in view and leaves the wearer to choose the tool.

The calibre is certified as a chronometer by the COSC, which tests it uncased, in a laboratory. Serica then tests the watch again once cased, a step it describes as rare. For a watch that carries the word chronometer in its name, on its dial and on its caseback, the checking thus goes all the way to the finished object.

The Expedition, a house bracelet

The Expedition bracelet, launched in 2025, was designed to fit the 8315 as standard. Serica describes it as merging the fine adjustability of the Bonklip, a bracelet born in England in the late 1920s and able to fit a wide range of wrist sizes, with the structured geometry of folded blades. The 316L steel is woven, folded and machined, with the same alternating finishes as the case.

Its clasp pairs a carriage that slides along the bracelet with a spring-loaded hook released by sliding the Serica logo. The adjustment, which Serica describes as micro-adjustment, covers wrists from 14.5 to 22 cm in a single size. Guilloché end-links join the bracelet to the case, and the house gives them a role beyond the functional, that of “turning the sports watch into a piece of jewelry born for heavy duty”. The line sums up the whole watch, an instrument willing to be a piece of jewellery too.

The ceramic gamble

Serica explains that every new ceramic shade takes it many months of development, with no guarantee of success. The material was chosen for its high resistance and light-reflecting properties, and the 8315’s insert is monobloc, a single piece of polished ceramic joining ivory and Golden Green, which the house regards as a true technical feat.

This green is warm and bright. Depending on the light, it shifts from golden beige to a very pale almond green. It answers the olive green enamel dial, with its powdered gold lettering and yellow gold accents. The extra-domed indices are in Super-LumiNova C3.

To describe this green, the house reaches for memories rather than a colour chart.

To us, it is the golden hour that makes everything seem more beautiful. It is the silhouette of this sports car we dreamed of as children, and the warm tone of that electric guitar that somehow always sounds better…

What it tells us

Travellers no longer need a watch to know what time it is at home; their phone tells them. The GMT has nonetheless survived that obvious fact, and the 8315-3 shows how. Serica takes care of the function, with a bezel that shows day and night without calculation and a hand you cannot mistake. But it presents the watch as an object of memory, one that “carries all the memories you are about to create”.

The Golden Green takes that logic all the way to colour. Months of development, for a shade that evokes the light at the end of the day, and a watch sold at the same price as its two earlier versions, 2,090 euros. The travel complication remains a tool, and it is through emotion that it renews itself.

The art of travel, Serica says, always brings us back home. Its name came from the edge of the map; its new bezel is the colour of the hour when you head back.
