While we wouldn't recommend it for determining if you're good to drive, the Kisai Breathalyzer Watch ($100) could make for some pretty interesting bar games. After breathing into the side of the watch, an LED backlight responds, turning green if you're sober, yellow if you're tipsy, and red if you're drunk — as well as displaying your BAC percentage. The stainless steel watch has an adjustable band and a USB-rechargeable battery that lasts for a month on a charge. It also displays the time, of course, so last call won't sneak up on you.
With the Summer coming, you're sure to find ample opportunities to get wet at the beach (or lake, river, creek, swimmin' hole). While a sturdy dive watch will withstand a plunge, they're probably a bit nice to take tubing — and most don't look anything like the Swatch Scuba Libre Watches ($90). These Swatches feature outrageous color combinations, swappable bands, quartz movement, and water resistance down to 200 meters. While you probably won't wear one diving, it'll definitely look good by the water, and at that price you won't be too concerned if you leave it in the surf.
You've seen this year's crop of Flight Instruments, and now it's time to see the complete collection. The Bell & Ross Flight Instruments Collector's Box ($32,900) includes all six of the highly-limited "instruments" — the BR 01 Heading Indicator, BR 01 Airspeed, BR 01 Climb, BR01 Horizon, BR01 Altimeter, and BR01 Turn Coordinator — encase in a handsome wooden and metal presentation box, with a numbered plaque, as well as holes in the top to allow the faces of the timepieces below to show through. Only 99 boxes are available, so if you're looking to add these to your collection, you'd best get a move on.
