MERIDIEN Quartz Caliber M1811 (case back), Battery Renata 362
Front	Dial	Back

Piquot
I do not have much information about the Piquot brand right now. I will add information as it becomes available. I can however tell you why I bought the watch. I was impressed with its single piece case and the "Swatch-like" battery cover that makes changing the batteries very easy. The watch is only about 34 mm in Diameter and that size clearly puts it into the 80ies. I have added the movement information M1811 as there is a marking on the case back. The watch needs to be opened through the front by lifting out the crystal.
