Product Details
The new Clifton Baumatic models reflect the gentleman’s world in all its splendour. The bright opaline salmon-hued dial sculpts each hour and calendar indication. The riveted, faceted, rhodium-plated indexes are shaped like slightly elongated trapezoids. An Arabic numeral appears at 12 o’clock. The faceted, rhodium-plated hour and minute hands are alpha-shaped. The oxidized black seconds hand offers a delicate contrast. The date appears in a wide aperture at 6 o’clock. The black minute track frames the dial.
The new proportions – a diameter of 39 mm and a thickness of 11.22 mm – bring finesse to the round case, crafted in satin-finished stainless steel like the crown. Fastened with four screws and covered by a sapphire crystal, the case back bears the special engraving “Limited Edition One Of 350.”
