Five Sporty and Stylish Cardio Wrist Watches
The house of Sector offers five watches from Cardio series. Each of them is powered by Miyota digital quartz movement and provides 50 meters (165 feet) of water resistance. They all feature plastic oval cases and comfortable rubber straps with buckles. The only distinction is in their design, as well as in their sizes.
Although the manufacturer marked all Cardio models as unisex, I am sure that the model R3251173615 that matches pink case, as well as a pink silicone strap is not appropriate for an average man. Another chronograph watch with the referent number R3251173515 is also created to improve the fitness routine of a modern woman. This is the same watch as the previous one, and the only distinction is white color instead of pink. Each of these two ladies’ chronograph watches can be purchased for $162.

There are also two larger versions. The exceptional model R3251173115 sports a silver bezel and a black rubber strap. The case of this chronograph timepiece has 40 mm in diameter and it is 15 mm thick. These two versions are priced $108 each.
