Claim to fame Mr. Aubert won the 2024 edition of the F.P. Journe Young Talent Competition, an annual contest organized by the brand to help students and recent graduates establish themselves in the world of independent watchmaking.

The winning watch Séléné, named for the Greek goddess of the moon, is a 43-millimeter timepiece that is wound with a key. “When you release it,” he said, “a shooting star rapidly moves across the sky” on the back of the stainless steel case.

One of the prize’s jury members, the Swiss independent watchmaker Marc Jenni, wrote in an email that Mr. Aubert had “outperformed in his approach to translate and display the technical aspect of the movement into a beautifully and well-designed wristwatch. He pushed the boundaries of aesthetical balance and sharp design. All details are meticulously finished.”

Its development Mr. Aubert made the watch — known as a montre-école, or school watch — during his seventh and final year of the prestigious program at Lycée Edgar Faure in Morteau, France. (The 2023 winner, Alexandre Hazemann, also graduated from that program.)

A challenge From the initial sketch to the watch’s completion took seven months of work — two weeks of which was spent solely on boring two small keyholes in the glass over the case back, one to wind the watch and the other to set the time. “I had to find a manufacturing process that would allow me to cut through the glass precisely enough without breaking it,” Mr. Aubert said, adding that he cracked more than 10 pieces of glass before succeeding.
