Making noise since its introduction in Baselworld 2012, the reference 5235 Regulator was Patek Philippe’s first ever wristwatch of its kind. Featuring a two-tone brushed silvered dial with blue accents in a symmetrical vertical dial layout, it is unique in its own aspect.

One of the unsung heroes of modern watchmaking, the model is remarkable both under an aesthetic and a mechanical point of view. Aesthetically, the case strongly echoes that of hallowed ref. 3448 (and its evolution ref. 3450), defined by sharp, futuristic shapes - in this instance however to a modern 40mm diameter. The dial two-tone is a masterpiece of design, superbly elegant and enormously understated. Even the Patek Philippe signature is subtly engraved on the dial, rather than etched, amplifying the understated nature of the watch.

The movement was especially designed for this reference and is similar in architecture to no other calibre made by the brand. Notably, it is the first serially produced Patek Philippe calibre to incorporate three silivon components developed by the Advance Research department: a silicon escape wheel, a silicon anchor and a silicon balance spring.

Preserved in excellent condition and offered without reserve, the present example in white gold is no longer in production as it is replaced with a pink gold version. Adding to its attraction, the present excellent example is further accompanied by the full set of accessories.
