There are a lot of different models of Cartier but I cannot imagine a more luxurious and feminine watch by Cartier. This Trinity is very clean and works well. The original buckle is present, in 18k Gold. The band pictured was replaced with a near new glossy lighter blue strap (Pictures will be updated asap).
