I ordered this watch Casio because I wear every day for 5 years began to accuse his age aesthetically but it works well without ever having changed the battery. I took an analog and digital clock. This bright field EFA 12D is perfectly readable. I have not had trouble adjusting it according to the instructions is in French. The document is a mini booklet is quite difficult to read, I went on the site to download casio more grand.Il is nothing on the strap adjustment but it is easy to adjust, simply push the pins in the direction of the arrow with a screwdriver or a very fine needle. The watch is very nice but I find it a bit small, 4 or 5mm more would have been ideal. For delivery all went well as usual with Amazon.
