ABOUT GMJ

Guillaume de Breyne is the founder and the person behind GMJ Watches. Born in 1996, he discovered his passion for watches in 2019. What started as a simple interest quickly turned into a deep fascination for horology, leading him to spend countless hours learning about watchmaking, iconic models, and the stories behind them. Over time, this passion grew strong enough for him to turn it into his profession.

Guillaume is especially passionate about vintage watches. For him, these timepieces represent much more than just a way to tell time. Vintage watches carry history, craftsmanship, and character that modern pieces sometimes lack. Every watch reflects the era in which it was made and tells a unique story about design, engineering, and the people who wore it before.

Through GMJ Watches, Guillaume aims to share this passion with other collectors, enthusiasts, and people discovering the world of watches. His goal is to offer carefully selected timepieces while building trust through honesty, knowledge, and attention to detail. For him, it is not only about selling watches, but also about preserving and appreciating the heritage behind them.

Among the many watches he admires, one stands above the rest: the Rolex Daytona Paul Newman. To Guillaume, this watch represents the perfect combination of sportiness, design, rarity, and history. The Paul Newman Daytona is not only one of the most recognizable vintage watches ever created, but also a symbol of the incredible stories that can exist behind a single timepiece.

With GMJ Watches, Guillaume continues to pursue his passion every day, discovering remarkable watches, learning more about their history, and sharing them with people who appreciate the timeless beauty of fine watchmaking.
