THEY REDEEMED THEMSELVES IN A BIG WAY
Around a month after GRJD replaced the battery in my watch, the watch conked out. They cheerfully replaced the battery, no charge.
It could have been a bad battery or my watch is messed up. It wouldn't surprise me if the two-year-old Casio has already outlived its usefulness. The world revolves around a throw-away paradigm.
Replacing watch batteries isn't a profit center. Jewelers probably do it only to generate goodwill. GRJD went out of their way to be gracious and welcoming.
