Despite the good service, these batteries are crap. I’ve had to replace them twice; both sets died within 6 – 8 months. Normally batteries for these particular watches last for years. Both Jessup’s Jeweler(downtown Melbourne on 5th) and the Jewelry Doctor(Eau Gallie & Highland) still replace batteries for $ 5 each. I will never return here for batteries, but may shop for jewelry or watch-bands. It’s disappointing because he was very friendly & efficient, but in the end that only goes so far.
