Over the decades a few watches have challenged established ideas and pushed mechanical engineering forward. Some have gone even as far as to change the way the industry thinks about precision, design, engineering and more. Here are 5 timeless watches to know that represent different milestones in horological history, from the Rexhep Rexhepi Chronometre Contemporain, F.P. Journe Tourbillon Souverain, Philippe Dufour's Grande et Petite Sonnerie, the Patek Philippe Ref. 5004, and the Seiko Quartz Astron. Each watch has a story that makes it worth knowing.
The Chronometre Contemporain I, introduced as recently as 2018, established Rexhep Rexhepi as one of the most compelling names in independent watchmaking. Its grand feu enamel dial, elegant case and manually wound movement give it a distinctly classical appearance. It is the detailing that is extraordinary. The hacking seconds function with zero-reset allows the seconds hand to return to zero when the crown is pulled, making precise time-setting easier. With a 100-hour power reserve and meticulous hand-finishing, the watch balances traditional craftsmanship with practical innovation. The watch won the Men's Watch Prize at the 2018 Grand Prix d'Horlogerie de Geneve.
The F.P. Journe Tourbillon Souverain was launched in 1999, and Francois-Paul Journe paired a tourbillon with a remontoir d'egalite in it. This acts as a constant-force mechanism that delivers more consistent energy to the escapement. The idea was to improve timekeeping precision rather than simply add another complication. Later versions introduced deadbeat seconds, giving the seconds hand a one-second stepping motion. The watch reflects and understated design, technical ingenuity and a clear purpose.
When it comes to complicated wristwatchmaking, the Philippe Dufour Grande et Petite Sonnerie comes to the fore. Developed in the early 1990s, it brought a grand sonnerie mechanism, previously associated primarily with pocket watches and clocks, into a wristwatch. It can automatically chime the hours and quarters in grande sonnerie mode, switch to petite sonnerie mode, or remain silent. A minute repeater also allows the time to be sounded on demand. What did it take to craete this watch? Well, painstaking hand-finishing and an extraordinary mechanical coordination.
The Patek Philippe Ref. 5004 watch combines a perpetual calendar with a split-seconds chronograph. It was produced from the 1990s until 2012. The calendar in the watch tracks the date, day, month and leap years, while the rattrapante chronograph can time two events that start together but finish separately. At approximately 36.5mm, the watch brings an unusually complex movement into a relatively compact case. This watch represents Patek Philippe at its most technically ambitious. And this was done without abandoning its classic design language.
The Seiko Quartz Astron 35SQ was the world's first commercially marketed quartz wristwatch. It was released on Christmas day December 25, 1969. Its accuracy of approximately five seconds per month was a remarkable achievement at the time, outperforming conventional mechanical wristwatches by a substantial margin. The original model had an 18-karat yellow-gold case and cost 450,000 yen at launch. More importantly, the technology behind it helped set off the quartz revolution, transforming how watches were manufactured, priced, and worn around the world. While the other watches on this list celebrate mechanical artistry. What makes the Seiko Quartz Astron 35SQ special is that it changed the direction of the industry itself.
These 5 watches show that watchmaking has been moved forward by those willing to challenge convention and rethink what is possible. And that is why they are remembered for generations.
