I have a Thommen, analog 19 jewel, 15000 ft altimeter for sale. It's in excellent physical and working condition. $120 obo. The instrument is so sensitive to altitude changes you can actually watch the needle move as you walk down stairs. I bought it many years ago for an exploration trip into Holloch in Switzerland. It is accurate to within 10 ft and is probably the best on the market. A lanyard is attached for wear around the neck.
