OMEGA De Ville Mini Trésor

Omega's De Ville Mini Trésor, reference 428.55.26.60.99.001, is a compact 26 mm case in yellow gold. The case measures 7.46 mm thick with a lug-to-lug span of 31.13 mm, small enough to sit neatly on a narrow wrist. A quartz movement, calibre 4061, drives the watch and includes a "Long Life" feature that extends the battery to around 48 months. The dial is yellow and sits under a domed sapphire crystal with antireflective treatment on the inside. This piece is set with diamonds, giving the case and dial a jewelled finish. The bracelet is also yellow gold, matching the case. Water resistance is modest here, rated to 30 metres, enough for everyday wear but not for swimming.
