Today I tried on some Bulova watches. I liked the Curv models, but I am a bit worried about the rubber strap. I had a couple of rubber straps break from too much wrist time and rubber deteriorates over time. The saleslady said, I could easily replace the rubber strap with a leather strap or even a bracelet, just unscrew it and replace it, but is that true? It didn't look like a normal mechanism to me.
