Tool watch

A tool watch is a wristwatch designed with additional functions meant for special job-related functions.

Most tool watches are designed for specific professions

• Pilot's watch (for commercial pilots)
• Flieger (for military pilots)
• Engineer watch
• Dive watch
• Field watch
• Sailing watch

Furthermore, for sports that require extreme performance, such as

• High-altitude mountaineering
• Speleology

Some “tools” are considered complications (if they involve time-keeping), while others are not. Here are some examples of watch tools

• Chronograph timers
  • Regatta countdown
  • Split-second hand
  • Flyback function
• Chronograph bezels
  • Immersion timer (diving)
  • Pulsometer (heartbeat)
  • Slide rule (pilot calculations)
  • Tachymeter (ground speed measurement)
  • Telemeter (rangefinding)
• Environmental monitoring
  • Altimeter
  • Depth meter
  • Barometer
  • Temperature gauge

Although many watches have such tools, a watch is considered to be a “tool watch” if it was specially designed for these functions.

Some famous watch models were designed as trade tools

• Breitling Navitimer
• Omega Speedmaster
• Rolex Submariner
• Seiko Speed Timer
