If you happen to look at Rolex Lady Date in a jewelry store window or glance at the wrist Rolex Lady Date of a friend, you can readily identify if the Rolex Lady Date you are looking at is a mechanical or quartz model.

The next issue is finding the correct size Rolex Lady Date battery, and finding a shop where the battery can be changed properly without damage to the Rolex Lady Date. Although the battery may only need replacing once every year or three, it is a given that this event will most likely occur at the most inconvenient time.

Statistically, the useful lifespan of a mechanical Rolex Lady Date is far greater than that of a quartz Rolex Lady Date.
