In addition to making a stylish statement and keeping time, well-functioning watches can alert their wearers to slight barometric pressure changes and must-see fourth-dimension drag races. Don't miss a second with today's Groupon to FJK Jewelers, redeemable at the North Pace Boulevard and North Davis Highway locations. Choose between the following options:

• For $5, you get a watch-battery replacement (a $10 value).
• For $10, you get $20 toward watch or jewelry repair.

Owned by jewelry juggernauts Frank and Michelle Kelly, FJK Jewelers keeps watches punctual and bodily bling snug, clean, and worthy of any special occasion. The experienced staff performs all bauble wizardry in-house, swapping out timepiece batteries and adjusting bands ($6) while the wrist-owner waits. Haul in a treasured ring in for adjusting down one size ($15+) or up one size ($22+ for women, $30+ for men), or have a small 10-karat lobster clasp ($18) repaired to finally get some mileage out of a live-lobster pendant.
