Actually, the RC watches may or may not be the best, depending
on what measurement you use. Here are accuracy plots

Probably my favorite watch ever is the Abicus Wrist PDA. While it is
not inherently extremely accurate, the battery is only good for a day
or two without recharge, so normally you connect it to a USB port
every night for charging/HotSync... at which time it resets to the
clock of the computer you'r

Hey y'all,
Interesting site but he's kinda behind the times, so to speak :-)
about what modern, more pedestrian watches can do.

Hey y'all,

Back around Christmas I bought a Luminox dive chronometer, model
3HMBM. This is the one with the chrono functions in the form of a
little LCD screen under 12 o'clock.
Jim;
I would suggest that the most accurate self contained wrist watch you
can get is the Synchronar 2100 Mk IV, after you've adjusted it.
It uses a fairly high frequency crystal (~700 kHz or so as I recall),
and a digital divider you can set externally, in increments of 8
seconds per year.

hi jim, here's the thing you were asking for:

Hi Folks,
What is the most accurate wrist watch you can purchase? Obviously the
radio controlled ones are the best, but I'm curious as to the fully self
controlled units.
Oh and yes I have seen the photo of the caesium clock attached to
someone's wrist!
Also, on the NIST website they talk about
