When their batteries are about to die, watches run erratically, slow down, and eventually make instinctual journeys to their final resting places beneath Big Ben. Keep time from running out with today's Groupon to Precision Time. This Groupon is valid only in Seattle. Choose between the following options:

• For $19, you get $40 worth of watches and watch-repair services.

For more than two decades, Hugo Fraga and his family have restored and fine-tuned the intricacies of customers' timepieces in Precision Time's convenient mall stores. In addition to replacing batteries and manicuring the hands of more than seven million watches, the millisecond specialists carry a full spectrum of watches and wristbands by designers including Swiss Military, Invicta, and Casio. A collection of Sottomarino timepieces ($39–$599) bestows wearers with craftsmanship infused with contemporary and traditional flair, and a collection of London Underground watches ($36) pairs classic and modern styling typical in across-the-pond fashion. Precision Time connects each of its functional jewelry pieces with a five-year battery plan and provides watch-cleaning services ($10) for timepieces that have gotten into scrapes with job-stealing cell phones.
