This is a late entry for HUMPDAY, yesterday; it was our 48th wedding anniversary & wanted to spend time with my wonderful wife. Today, right now, is HUMPDAY, which features the older version of my TAG HEUER, which is the 500m version -- not the 300m version of the newer one; this older one is a quartz powered one and not an automatic one. It's heavier than the 300m version; and like the newer one, was purchased while on a cruise back in 2010. What's amazing out the 500m oldie is its battery: after ten (10) years of (none constant) usage, its RENATA battery died last year. Amazing! dave:
