Do pocket watches exist and how much do they cost in d&d in the worlds of classic fantasy?


Do pocket watches exist, how much do they cost and how much do they weigh in d&d in the worlds of classic fantasy? Like Faerûn, Dragonlance, or Greyhawk? I am interested in the ability to track time up to a minute.

I have found the following comment of Ed Greenwood on sageadvice, according to which the wealthy merchants, nobles and warehousekeepers use pocket watches most often in the Realms, and that it is customary to wear watches on a chain around the neck, not on the wrist. But I could not find the recommended price and weight for a pocket watch in the official materials.

Editions from 2nd to 5th are of interest. If you manage to find this information, please mention to which edition the material that contains it belongs, if possible. Thanks.
