The lettering on all keys is very clear so may not have been used greatly. I do not think that the strap has been adjusted and is full length so will fit upwards of an 8.5 inch wrist. Overall a good example of this watch. The pictures are part of the description. I do not know when the batteries were last changed but do not have the tool to open the back to change for fresh ones before posting.
