Audemars Piguet Royal Oak 26735St.Oo.1320St.01 Selfwinding Flying Tourbillon Openworked “50Th Anniversary” 41Mm Stainless Steel

The Audemars Piguet Royal Oak 26735ST.OO.1320ST.01 is a statement piece created to mark the 50th Anniversary of the Royal Oak. This is not just another anniversary edition. It’s a watch that strips the Royal Oak down to its mechanical core and proudly shows everything that usually stays hidden.

Crafted in 41mm stainless steel, the case keeps the iconic Royal Oak proportions intact. The sharp bevels, brushed surfaces, and polished accents remind you why this design has survived for five decades without losing relevance. On the wrist, it feels purposeful rather than flashy.

Openworked Dial And Flying Tourbillon

The openworked dial is where this watch truly separates itself. Instead of a traditional face, you’re given a full view into the movement’s architecture. Bridges, gears, and the flying tourbillon all exist in plain sight.

Positioned at six o’clock, the flying tourbillon appears to float, supported only from beneath. It’s a technical achievement, but more importantly, it creates visual balance. Despite the complexity, the dial remains readable and surprisingly calm. Nothing feels overcrowded.

Calibre 2950 And Wearability

Inside beats the in-house Calibre 2950, an ultra-thin automatic movement developed specifically for openworked tourbillon models. It’s finished to Audemars Piguet’s highest standards, with hand-applied details visible from every angle.

Even with a high complication, the watch wears comfortably. The slim profile and integrated stainless steel bracelet help it sit naturally on the wrist, making it suitable for regular wear, not just special occasions.
