Actually, the strap release mechanism was developed and patented by IWC, which is the system used here I believe. IWC is a sister Richemont Group cartier replica roadster watches brand along with Cartier, and IWC licensed this technology to Cartier. I included a nice closeup image of the strap release mechanism. The strap is fine, but the clasp is where the issue is. First, the system of tucking in strap excess to hide it is good in theory. However it uses a basic tension system here with nothing really securing it. What this means is that the strap will loosen over time, or if pulled on. Forcing you to "tighten" it. The straps tuck in on both sides of the clasp to ensure you can position the clasp at the bottom of your wrist. Wearing the watch, I found that I needed to occasionally adjust it for a good fit. It is easy enough to do, but isn't a perfect system for a luxury watch. This isn't an issue of course with a metal bracelet, but at least with the strap you can afford yourself a more precise fit.
Super classy. The cartier replica roadster chronograph watches hands are *** and legible, with applied SuperLumiNova.Inside the watch is Cartier's automatic Calibre 049 - which I believe is a base ETA 2892 movement. A solid movement that works fine, but isn't anything fancy. It is a good movement to have in a sport watch given its relative level of durability. While this is no action-adventure watch, with its lighter weight, 100 meters of water resistance, and secure fit on the wrist, you could easily be "active" with the watch and not have it impede you too much. Though I tend to not recommend people do wild things in nice watches.I don't have many issues with the watch, but I have a few quips about the rubber strap. One thing I do like is Cartier's use of quick release on the case for the straps. You can easily remove the straps (or bracelet) without any tools from the case. That is a good touch, and the system on this cartier replica santos 100 chronograph watches works well.
