Aquamarine 45C Swiss Chronograph
My Aquamarine 45C is a good-looking watch but unfortunately the accuracy is not so good. Panzera is claiming that the watch is “certified to the highest levels of accuracy” but no certification of accuracy is delivered with the watch. One of the biggest reasons for buying an Aquamarine 45C was that I believed that this Swiss made watch was coming with a COSC chronometer certificate. A mail from Bernadette said “Yes, the Aquamarine 45C Chronograph does come with a Chronometer Certificate included in the package”, but only a certification of origin is delivered with the watch. The Aquamarine is using the Swiss Valjoux 7750 movement that exists in three different grades. A Chronometer Certified watch is only equipped with the top-grade movement that has the highest levels of accuracy. However, the 7750-movement equipped in the Aquamarine 45C is the lowest grade called Elabore. The 7750 grade Elabore is stated from the manufacture ETA to have an average daily rate (mean value for 3 different positions) within +/- 5 s/d, but my watch has a value of +12 s/d that is more than twice the specified maximum rate for this movement.
