Many vintage watches had 19mm lug widths due to imperial measurements used at the time, 19mm is 3/4 of an inch so it was a convenient value to use at the time.

Post metric standardisation, 19mm seems like an odd width to use. Many watch companies such as the ones above still use 19mm on 39mm watches because an 18mm strap seems too narrow by todays standards and 20mm would be disproportionally wide for a 39mm watch.
