It is impossible to overestimate the challenge of making ultra-slim watches that embody the Discreet Luxury motif. Makers have to design new ultra-fine components, such as micro rotors. They must manufacture them, and fit them around each other perfectly, while maintaining structural integrity and stress tolerances. Some components are as thin as a hair.

Last year, the brand set a new record for the slimmest automatic chronograph with an added GMT function on a sub-dial, featuring a horizontally-coupled, column wheel chronograph housed in titanium, a model that's returned this year in titanium with an all-black dial display, minus the GMT function and in sandblasted titanium.

The design was stunning, given the energy the chronograph seconds reset provides and the challenge to ensure the chronograph gears mesh perfectly with the gear train in order to avoid the dreaded "bounce" that is common to horizontally coupled watches. The brand took on the challenge with casual aplomb and renewed it this year.(https://www.rolexgrade.me)

In the eight years that have passed since the Octo's introduction, thanks in part to the incredibly innovative changes made to Genta’s original vision, it has amassed a number of world records based on its thinness, including: the thinnest automatic movement (2.23mm), the thinnest tourbillon (1.95mm), the thinnest minute-repeater (3.12mm) as well as the thinnest chronograph (6.90mm). The Octo is available in many different versions, including extra-thin, tourbillons and skeletonised. There are also a variety of materials, bracelets, straps, colours and styles.
