In the 1970s, Piaget wasn’t trying to make the toughest watch in the room. It was doing the opposite: crafting ultra-thin, precious-metal pieces with a level of finishing and refinement that few could match. The hobnail (also known as Clous de Paris) pattern is a perfect example of that philosophy: a deceptively simple texture that turns a clean, minimalist watch into something that constantly plays with light and looks far more expensive than its size suggests.

This reference 9123 captures that era beautifully, pairing a slim, square profile with a hobnail dial and matching hobnail case, executed in 18k yellow gold and powered by a manual-wind Piaget movement to keep everything razor-thin on the wrist.
