The Bulova Ladies 21 Jewel Automatic uses the motion of the wrist to wind the mainspring of the watch. In turn, that power reserve drives the intricate gears that regulate the time and create the rotation of the balance wheel, the "heartbeat' of the watch. The balance wheel oscillates 5 rapidly, 5 times each second, and can be viewed from the front or the back of the watch, as shown on the left.

Bulova's designers have created a beautiful watch, also keeping in the tradition of Joseph Bulova. The watch face is adorned with 44 beautifully matched diamonds. The dial itself is created from genuine mother of pearl.

The watch case and bracelet are made from stainless steel for incredibly durability and a lifetime of wear. The front and back crystals are scratch resistant hardened mineral glass. The watch is water resistant to 30 meters or 100 feet below sea level.

If you are looking for an heirloom quality watch with both beauty and elegance, the new ladies Bulova Heartbeat Automatic mechanical watch is an ideal choice.
