A1. A clock in a swivel.
A chronometer is an accurate clock which has a reliable and predicable rate of error.
The set of gimbals, are two rings around the clock, joined together at 90 degrees by swivel joints.
This arrangement allows the clock to be level whilst a ship rolls, it also allows the clock to be turned upside down to wind it up with a key. This of course would only be relevant to clockwork mechanisms, in order to stop the ships motion affecting the clockwork movement.
So, a gimballed chronometer is most likely to be found on a commercial ship.
More modern chronometers use a quartz movement and so don't need gimbals.
A2. Although the instrument keeps level, there are still acceleration forces acting on it, as the ship moves. It is remarkable that mechanical devices can be made so resistant to these external forces.
A chronometer measures time. Generally, only a clock that is extremely accurate would be called a chronometer.
If you mean a timepiece the answer is - Chronometer. If you mean 'look at' the answer is - observe.
To calculate distances, based on speed of sound through air, when observation is both visible and audible. The moment the event takes place, the second hand is started, then stopped when the sound is heard. The corresponding reading on the scale denotes in miles or kilometers (as indicated on the scale itself). The telemetric scale was used by the military as a crude range finder. When the enemy artillery's muzzle flash was seen, the chronometer was started and when the firing was heard, the chronometer was stopped. The second hand pointed to the distance away. source: http://forums.watchuseek.com/showthread.php?p=1552491#post1552491

"Chronometer" is a noun.
A stove. Hopefully, a gimballed stove!
Chronometer Chronometer
she frequently referred to use a clock as a chronometer Meaning chronometer is a more accurate word for "clock" :)
A chronometer is a watch that is designed for the highest amount of precision and accuracy. The time on a chronometer watch is almost always accurate.
She frequently referred to any clock as a chronometer .

No, not all Rolex chronometer watches are chronographs. A chronometer is a watch that has been certified for its accuracy and precision, while a chronograph is a specific type of watch that features a stopwatch function. Rolex offers both chronometer-certified watches and chronographs, but these features are not inherently linked; a watch can be a chronometer without having a chronograph function.
Long before GPS, an accurate chronometer was needed to help a ship determine Longitude.
No, not all Rolex watches are Chronometer certified. Rolex offers both certified and non-certified models in their lineup. Chronometer certification guarantees accuracy within specific standards set by the Swiss Official Chronometer Testing Institute (COSC).

No. A chronometer measures time. Wrist watches, egg timers, and hour-glasses are chronometers.
