Object description

Case and Dial

The watch is housed in a 42mm steel case protected by a PVD coating. According to the vendor, this coating has aged, shifting from its original black finish to a dark grey appearance. The case is fitted with a fixed bezel featuring a tachymeter scale.

The black dial is configured with three sub-dials for chronograph functions and features luminous hour markers. A central chronograph hand, described by the vendor as having faded over time, provides contrast against the dial surface. The three o'clock position houses a window displaying both the date and the day of the week, with the latter presented in French.
