One day I will own one of those vintage Seamaster 300. It is one of the few divers that calls out to me.
For today I will have to suffice with a King Seiko. Just returned from watchmaker because its hairspring was stuck together.
This one has the chronometer grade movement in it even though it is not marked on the dial.
Mrs. Blufinz and I stopped at the Swift River on the Kancamagus Highway today. While we soaked our feet in the cool water, we drink some Chardonnay. Absolutely perfect weather.
Usually, the crown has three positions. 1/ the run position where it stays when the watch is worn. 2/ one notch out, the calendar set position. Turn it one way to set the day, the other way to set the date. 3/ the time re-set position.
The first step in setting your calendar is to set the hands ahead until the calendar changes. Then set the watch to correct time AM or PM. Then set the calendar.
Some older calibers require that you set the hands ahead until the DAY changes, then set the watch to time. THEN follow step 2 above.
If this doesn't work, there could be something wrong.
