The "Richeville" collection, introduced in 1993, traces its roots to GP's tonneau-shaped watches. Its distinctive case, a fusion of round and square, has garnered fervent support from watch enthusiasts and fashion-forward individuals alike.

The "Richeville Day&Night" is a particularly unique model, displaying the hour via a pointer at the 12 o'clock position that indicates a disc rotating once every 24 hours. The disc, divided into two colors, not only simplifies distinguishing AM from PM but also serves as an effective design accent. The minutes are shown by the long central hand, and the seconds by a sub-dial at the 9 o'clock position. This separation of hours, minutes, and seconds further accentuates the individuality of the Richeville.

The inclusion of a power reserve indicator at the 5 o'clock position is another noteworthy feature, highlighting its practicality. It is powered by the in-house "Cal. GP033G0," and its beautiful movement can be admired through the sapphire crystal case back.
