In 2000, Citizen did a National Park theme in the Promaster Tough EcoDrive series. This is the Yellowstone version. The watch has a screw down crown. As it comes from the Tough series, it has increased antimagnetic protection at 16000 g, thick sapphire crystal and extra shockproofing. A solid well made watch excellent as a beater for outdoors. Citizen ti is also usually rather scratch resistant. In Japan, these watches does not seem very rare and often sell quite cheaply.
One piece titanium case and a nice caseback print.
Kevlar strap with metal keeper.
The other watch I found in this series was the Aoraki Mount Cook version, named after a National Park on the South Island of New Zealand. Pics and additional text from this bolg post (in Japanese).
