Reloj elegante!
Color: Anthracite on Stainless Steel
El reloj es bello, tal como se ve en la foto. Podría mejorar si tuviera mayor reserva de marcha, pero si lo usas todos los días a la misma hora, no tienes que darle cuerda o ponerlo en hora.

This is a fantastic watch!
Color: Silver - Stainless Steel
This is a fantastic watch! I have about a 6.25 inch wrist and the 42mm version fits perfectly. I had actually purchased the 38mm version and had to return in because it was too small. The dial is amazing and the beauty of the watch is its simplicity. Its face is uncluttered but has the main features that I need, time, day and date. Plus, the automatic movement is quite accurate and smooth. Overall, I would recommend this watch to anyone who wants a clear and uncluttered watch that is very easy to read!
