In June, in the Secunda store of the Vega shopping center, I bought a Casio G-2900 watch exactly six months later in December, a problem arose, in cold weather when my hand started sweating, the glass began to sweat, I took it under warranty to the store, waited two weeks, came in the warranty letter it says "drying".But the problem remained as it was, after the seller's advice to cover with a sleeve (the watch is waterproof), I realized that they were not engaged in any warranty repairs.Another point is that the documentation and the year of manufacture are not indicated on the box, the watch can lie in the window for years, and the battery is given a 10-year warranty.So be careful, the brand does not always match the quality.
