Watch easy to program despite the instructions in English or Spanish, fairly intuitive controls. And with concepts in 2 languages, there are no problems. Good reliable product, light but strong, good readability. Good size for adult wrist, great for teenager. Compass very correct, but does not use measuring instrument. Ideal for biking, walking uplands. The thermometer is to use a watch out of course wrist ... Very happy with this purchase, the watch I was waiting a long time. I'll just have preferred a rubber strap rather than resin.
