A method for controlling an electronic watch includes a first pointing hand, a first motor configured to move the first pointing hand, a second pointing hand, a second motor configured to move the second pointing hand, a pressure sensor configured to measure pressure, and a mode indication unit configured to indicate a mode, and when detecting start of diving based on a pressure measured by the pressure sensor, control is performed on the first motor and the second motor to indicate with the first pointing hand a water depth estimated from the pressure and indicate with the second pointing hand a time period of diving for which timing is started after detecting the start of diving, and when the water depth is indicated with the first pointing hand, with a plurality of modes with different indication resolutions being provided, the selected mode is indicated on the mode indication unit.

Provided is a timepiece including, in addition to a crystal, the following external elements: a back (2), a middle part (1), a dial (3), and two bracelet strands (30), at least one of these external elements includes a body formed of a first portion made of a first opaque material and of a second portion made of a second partially transparent or translucent material. The first material being integral with the second material and the timepiece also includes at least one light source (10) producing light which passes through the second portion made of a partially transparent or translucent ceramic material comprising zirconia.

A diving watch includes a first device for displaying the current time and a second device for analogically displaying a diving duration. The second device includes a hand dedicated to the indication of a diving duration and a rotating bezel provided with a visible face including a time scale including time graduations. The bezel cooperates with the dedicated hand, in particular continuously animated with a uniform rotational movement, by displaying an instant value of the diving duration.

The invention relates to a capsule comprising a shell containing a transparent and thermally conducting liquid, particles having a thermochromic coating and particles having a photochromic coating, the thermochromic particles being bulkier than photochromic particles, the liquid being such that, within a first range of temperatures, its density is greater than the density of the thermochromic particles and than the density of the photochromic particles, and such that, within a second range of temperatures greater than those of the first range, the density of the photochromic particles is less than the density of the liquid, which is itself less than the density of the thermochromic particles.
