I don't know if this post will work, but there is a simpler and cheaper way to put time on your wrist. A Casio Waveceptor Atomic Watch receives WWVB time from Fort Collins and Rugby, England each night. It switches to and from DST automatically and is generally accurate to within 1/10 second. The battery is specified to last for 2 years, but both of my watches have gone much longer. The Waveceptor watches are available at https://www.casio.com/products/watches/wave-ceptor starting at USD$39.95 Waveceptor Manual https://support.casio.com/storage/en/manual/pdf/EN/009/qw3054.pdf WWVB Coverage Area https://tf.nist.gov/stations/wwvbcoverage.htm Fort Collins, Colorado 60 KHz time signal https://en.wikipedia.org/wiki/WWVB Rugby, England 60 KHz time signal "https://en.wikipedia.org/wiki/Time_from_NPL_(MSF)" JJY in Japan also transmits on 60 KHz with a similar format to WWVB, but I don't know if the Waveceptor will receive it. It is not in the Waveceptor City Code. https://en.wikipedia.org/wiki/JJY There are 683 posts that refer to WWVB in the time-nuts archives.

I've owned two of the Casio Waveceptor watches and they are rugged and reasonably priced. I like a less cluttered face with no printed numbers on the analog clock face, a single rectangular LCD for the advanced functions, and a metal link band. The higher end Lineage line can provide titanium case and band for light weight and sapphire crystal for a ~250 USD, or the basic waveceptors with base metal or plastic case, stainless steel and regular glass crystal start, as you say, around 40 USD. Since politicians decide parameters of summer time, my model is old enough to support DST but not the new days, so I have to manually move it from DST on to DST off. It does support 24 time zones. I had a Citizen aviator watch but it was too heavy and busy to be practical for my wishes, and it disappeared at some point, I can't recall if it was stolen or misplaced in a move. I still have my Casios, though! With the proliferation of mobile phones, it does seem wrist and pocket timepieces are becoming a thing of the past (unless you mean a smartwatch or fitness tracker, oh I do wear one of those as well). My father has an extensive collection of railroad pocket watches, and my granddad did clock repair as a side business to maintaining time deposit safe clockworks, and here I am writing a ESP-32 FreeRTOS application to use SNTP and weighted linear regression smoothing with outlier rejection to design a smart home wall clock (so it can handle the DST changes for me throughout the house), so the interest in time runs in my family.

I have to echo Mike's comments. Been a WaveCeptor customer for a while, I own two. I have been watching the Citizen offering and I am intrigued by the offering, not sure the current budgetbwould allow the expense (recently retired). I have one unit thT MUST BE ABOUT 12 YEARS OLD NOW AND THE BATTERY IS STILL HOLDING ON, NOT SURE HOW MUCH LONGER THAT WILL BE THE CASE AND i MAY'VE JUST JINX'D it ;-) On Mon, 2021-09-13 at 18:19 -0400, Mike Monett wrote: > I don't know if this post will work, but there is a simpler and > cheaper wayto put time on your wrist. > A Casio Waveceptor Atomic Watch receives WWVB time from Fort Collins > andRugby, England each night.
