This previously owned Vacheron Constantin Malte Dual Time Regulator in 18K yellow gold with reference number 42005-000J is exemplary of the brand's craftsmanship. The 38 mm case surrounds a silver matte dial, a minute hand made of yellow gold, a small 12-hour indicator with roman numerals, a 24-hour dual time indicator, and a small seconds sub-dial with a date display. The hinged solid half-hunter case back engraved "Vacheron Constantin – Geneva" reveals a screw-down exhibition sapphire display case back secured by 6 screws that reveals the 65-hour power reserve self-winding automatic movement that drives the timepiece. It is fitted with its original black leather strap and a yellow-gold Vacheron Constantin pin buckle.
