PERFECT
Color: Black
Watch is light weight. Has a good feel on the wrist and easy to read during the day and easy to read with the indigo back light at night. I have large wrists and this size is good. For smaller people it might be to large. The functions work well and its water tight. Its durable and keeps on ticking.
