Who's afraid of tonneau-shaped watches?
These tonneau or barrel-shaped watches are not to everybody's taste, but I find them interesting and they share such a strong family resemblance:
- Patek Philippe Chronometro Gondolo (both vintage and modern ref. 5098)
- Franck Muller Casablanca (ref. 6850 SC)
- Vacheron Constantin Historiques 1912 (ref. 37001)
- Omega Petrograd 1915 (both vintage and modern renditions)
Enjoy!
