Room I · The Maker
No maker's name appears, but the case speaks clearly: 42 grams of solid 18K gold, hallmarked for Swiss export, and decorated in guilloché enamel on both faces rather than one, a genuinely uncommon thing. We present it for what it verifiably is, a heavyweight, doubly-decorated Belle Époque gold case in full working order.


The Object
A genuinely substantial 42g of solid 18K gold, with rare guilloche and enamel work on both the dial and the case back, not just one. Confirmed Swiss hallmark, fully running, ready to wear or display.
No name appears anywhere on this watch, and the case makes its argument on its own. It is solid 18K gold, 38mm and a full 42 grams of it, and it is decorated on both faces rather than the usual one. The back carries a fan of vertical engine-turned panels bordered in cobalt blue and white enamel, framed in chased gold scrollwork and topped by an oval cartouche; turn to the front and the same blue and white enamel runs around the bezel under pierced gold scrollwork, so the watch presents a finished face whichever way it lies. In researching this piece, no comparable example was found decorated to this standard on both sides.
The dial keeps the theme, in three textures. The centre is a basin of fine concentric engine-turned circles inside a beaded ring, the numeral ring is frosted matte gold carrying tall, stylised black Arabic figures of the Art Nouveau years, and the sub-seconds at six is turned in the same concentric rings. Over it all sit blued steel Breguet hands with the open ring near the tip: a dial made by the same instinct that decorated the case, with nowhere left plain that could be worked.
The watch is keyless, wound and set entirely through the crown, and it winds smoothly, sets correctly and runs well. The rose-toned pendant and bow sit warmly against the yellow gold of the body, and at 38mm it wears as easily on a chain as it sits in a pocket.
Enamel fired over engine-turning is fragile by nature, and both faces of this case have come through more than a century without a chip, a crack or a fade. That is the whole story of the watch: no famous name, and nothing to apologise for anywhere on it.
The marks, the movement and the condition are set out piece by piece in the drawers below; the enamel work is shown close in The Enamel.

Room III · The Enamel
Guilloché enamel, on both faces
The caseback carries a fan of engine-turned gold panels bordered in cobalt-blue and white enamel with chased scrollwork, and the same enamel border runs around the dial side, decorating both faces to a standard rarely seen. Fired over engine-turning and surviving a century without loss, it is the mark of a specialist workshop and careful ownership.
