HI all. this is my first post here. Have a question here that I hope the HEQ gurus might be of help with.
I purchased a ladie's fiance a lady Cartier Roadster quartz about 2 months ago. She only started wearing it and noticed that over 24h the watch is 15-20min slow. The watch seems to be running ok when left on the table but when worn begins to slow down. I am going to confirm that today by leaving the watch on the table all day and see what happens.
What can cause a quartz watch to run so slow? Could it be just a battery problem or something more serious? Is there anything special about the Cartier roadster movement (I assume it's a pretty standard ETA?)
