I bought a Casio ten years ago for 40 euros. But every year I change the battery for only 1.5 euros, even though it fell into the water and stayed on for a whole day. Repair for only 4 euros. And still this moment. good.
Why calling it Aqua Terra when Aqua Terra has numbered minute markers, sunburst dial, has no crown guard, and dial markers are pointed? Then it has date at six o'clock not integrated with a cut-off marker and so on. Also from the profile point of view, it is very diferent in sence of polishing, it has very differently formed crown an yes it does have an arrow formed hour hand and it is a minute hand that formes an arrow in case of Aqua Terra. Yes, there are always some similarities like all the dresses ever made have as people have only two hands, two legs and one neck. It might have been an inspiration but it is miles away from being an homage watch. Just my humble opinion. All the best...
