Re: Speedmaster Date 3513.50

: Hi Larry,

: I use the website in the link below, which is
: to the official US time clock. The first
: thing you need to do is synchronize your
: watch with this site. Then come back and
: check the time again after a week or so and
: see how many seconds your watch has gained
: or lost over the course of a week. You can
: then divide that number by 7 to get an idea
: on your watch's daily timekeeping.

: Since your watch is new, it is still in its
: "settling in" phase, so it may be
: a few weeks or a month before you start to
: notice its time gain or loss remaining
: consistent. -4 to +6 seconds per day is the
: COSC chronometer specification, and even
: though your Speedy Date isn't a chronometer,
: it is certainly capable of running within
: those specs.

: You can also experiment with different
: overnight positions to try to optimize your
: watch's accuracy. Every mechanical watch
: behaves differently, so it's all a matter of
: trial and error. You may find that your
: watch gains about 4 seconds a day while on
: your wrist, but it will lose a few seconds
: overnight while kept in a certain position
: (crown up, crown down, dial up, etc.). So,
: you can help "offset" any time
: gain or loss by experimenting with overnight
: positions.

: Part of the fun of owning an automatic watch is
: checking its timekeping and trying to
: optimize it. Since you have a new watch, you
: should be able to have some fun
: experimenting.

: Good luck,
: John

Thanks John. I am going to try that. I am already familiar with the website you have provided and have it saved in my favorites. I try this and let you know what happens. Thanks again!
