First launched in 1999, the Patek Philippe Twenty~4® Ref 4910/10 was the first Patek Philippe diamond-set ladies’ watch housed in a steel case. The metal, whilst highly practical and ideally suited for use every day, may on the face of it have appeared pedestrian for a brand synonymous with using noble metals. However, the boldness and bravery of the Genevan watch company were to be rewarded with incredible sales success.

The nomenclature of this watch makes reference to its ability to be worn all day, every day. Its styling lends itself to both casual attire as well as cocktail events and glamorous balls. This first reference was offered with a choice of three dial options at the time of launch, ‘Timeless White’, ‘Forever Black’ and ‘Eternal Grey’. The steel case of the inaugural model was set with Top Wesselton diamonds.

The model continues to feature within the current collection. The dial is set with diamond hour markers, save for 6 and 12 o’clock which are proclaimed with gold, applied Roman numerals. The convenience of a quartz movement proves popular with those wearers who dislike the notion of winding a watch after the power reserve has become depleted. The styling of the Twenty-4® takes inspiration from the art deco era but refracts it through a prism of modernity. The linearity of the gem-set bezel, diamond hour markers and straight caseband are repeated with the straight edges of the matching metal bracelet.

In 2000, Patek Philippe released a smaller case size option and gold variants of the Twenty-4®. The Ref. 4910/11, sharing the same dimensions as the 4910/10, was released in a sumptuous 18-carat rose gold case. It offered a choice of dials, including pure ‘Timeless White’ or rich, indulgent ‘Chocolate dream’. Again, these models continue to populate the range, perfectly illustrating that style never goes out of fashion.

A key competence of the Geneva watches brand is gem-setting and this is beautifully illustrated with the astonishing Twenty-4® Haute Joaillerie collection, where the case, dial and bracelet are spellbindingly adorned with optimally sized and positioned diamonds. In some instances, these creations dispense with matching metal bracelets and duet with gracefully hued satin straps which coalesce superbly with the finest haute couture creations.

While many prospective purchasers of the Patek Philippe Twenty-4® choose quartz models, equipped with the caliber E 15 movement, some would-be wearers still seek the mechanical allure provided by the reassuring tick of a Swiss lever escapement. The Caliber 16-250 is a hand-wound mechanical movement, imbued with the typical matchless finishing of Patek Philippe which engenders nods of approval from the cognoscenti. It is housed within the dainty feminine Ref 4909/50, measuring 22 x 26.3mm with a remarkable shallow height of only 6.8mm.

As the Patek Philippe Twenty-4® has illustrated since 1999, a timepiece that is suitable for use every day does not have to mean accepting an everyday watch.
