Very good watch for its price. I have had it for 12 years and I haven't changed the battery yet. I only replaced the strap all these years. Very lightweight, it loses very little time and as a bonus, it has an agenda where you can store a certain number of names with their phone numbers. As a downside, the glass scratches very easily, but with a whitening toothpaste and a little rubbing for half a minute, it becomes like new. Oh, and it is not 48mm but 40mm. Suitable for small and medium wrists. Excellent for its price!
