The selection of the wrist for timepiece placement is primarily a matter of individual preference and comfort. Convention often dictates choosing the non-dominant hand, allowing for ease of use with the dominant hand in everyday tasks. For example, a right-handed individual might opt to wear a watch on the left wrist.
Adhering to this convention offers several advantages. It minimizes the likelihood of the watch interfering with common activities, reducing the risk of scratches or damage to the timepiece. Historically, this practice also stemmed from the practicality of winding manual watches; the non-dominant hand held the watch while the dominant hand manipulated the crown.
