This is a very nice piece of chuck of metal from Cartier its from the Santos 100 series, this particular model is the biggest one they do XL and is a nice piece with chronograph and date function. The Santos 100 XL has a in house movement from Cartier and comes on a leather strap with a deployment clasp, watch has a lot of presence people tend to get them diamond encrusted to make it big with bling, unfortunately way to big for my wrists so never kept the the Cartier. My personal opinion, nice looking, great watch if you can carry it with bigger wrists, and not bad value for money.
