Goodness me! Nothing of the sort - my 'ritual' is to check the timing against a time-source for 3 or 4 days to check for accuracy - if it's mechanical that is - and within a few seconds per day. Else - nothing much - except take a few pictures for my records including any paperwork and upload for safe-keeping.
Finally - try and look nonchalant while wearing the newly purchased watch near SHMBO to avoid conflict!
