A Casio fills its functions very well: she has lost only five seconds in 1 month! Advantage: it is very readable and surprisingly light to carry. The compass works properly. Dates, alarms and stopwatch are easy to program. One can choose from several dates already scheduled country capitals. Hours Summer / Winter. Downside: as indicated in the instructions, the thermometer is distorted (5 ° to 6 °) body temperature. To obtain an exact temperature, remove the watch from the wrist (30 minutes). But is it really important for a watch? Compared with Emporio Armani Meccanico which cost me 400, which was rapidly losing 10 minutes per day and was heavy to carry to the wrist, this Casio is an excellent price / quality ratio. A purchase I recommend it for those who like quartz watches!
