A comprehensive outdoor watch.
This watch has everything you might need to navigate your hill walks. The various functions take a bit of learning and practice but are easy to access once you are familiar with it. It is of very good quality and it is comfortable on the wrist. Avoid the instructions that come in the package, instead get the pdf or online version. E.g. the temperature can take 20 minutes off the wrist to give an almost accurate reading. The attached is a picture of the compass. I use this function the most.

En el año 2021 compré un reloj Casio twin sensor por 45 dólares, la medición de altura es muy buena, no obstante, la medición de la temperatura es muy mala, creí que al comprar un reloj casi 4 veces más caro y especialmente diseñado para realizar deportes de montaña, como es el Protrek, la precisión de las mediciones iba a mejorar. Ya voy usando más de una semana este reloj y me ha decepcionado, la medición de altura es mala y la de temperatura es mucho peor, más allá de ser un reloj bonito, los sensores que lleva no cumplen con su función de manera aceptable o es que tal vez haga falta calibrar los sensores, no lo sé. Me siento decepcionado de la compra.

Bought to replace my 13 year old Casio Pro Trek. Power was on "M" so put it on the window sill in direct sunlight and 3 days later it was still on "M". My old one goes from M to H after a few hours. Return
