Radio control is nice, but it isn't globally compatible.

In europe most of such device rely on the 77.5 kHz signal from frankfurt, but other frequencies are used outside of europe, and timepieces will likely not be compatible with (all) of those.

NTP synchronised clocks are more accurate though as they factor in propagation delay, wheras radio controlled ones do not. The error would be far under a second for DCF77 within europe though, so no problem for a wristwatch.

I have no idea what frequencies mine is compatible with, but I know it works in Europe and USA.

Probably at least a few, which is good.

A lot of european radio clocks only took the dcf77 signal, but i think those were popular somewhere back in the 90s - i remember having one of those little radio controled lcd clocks (not a watch, though it was almost small enough to be used as one).

That's good. I'll try and find out because I'm curious now.

Time to update my Watch collection.
Bought this second hand Seiko 7T62 Chronograph at an antique store yesterday.
My family and I went for a three hour drive down south of Sydney and visited these little towns that are a tourist attraction for antiques and old town attractions.

Found this nice white faced Seiko in the display and loved the look.
It came in this nice little hessian bag.
The thin red hand is the stopwatch function and when you press reset it races around the clock face till it comes to a stop back at 12 o'clock, very cool.
Hope you like it.

For God so loved the world that He gave His only begotten Son, that whoever believes in Him

For God did not send His Son into the world to condemn the world,

but that the world through Him might be saved.
“He who believes in Him is not condemned;
but he who does not believe is condemned already, because he has not believed in the name of the only begotten Son of God.
And this is the condemnation, that the light has come into the world, and men loved darkness rather than light, because their deeds were evil.
For everyone practicing evil hates the light and does not come to the light, lest his deeds should be exposed.
But he who does the truth comes to the light, that his deeds may be clearly seen, that they have been done in God.”
(John 3:16-21)
─────────────────────────────────☀
If you confess with your mouth, “Jesus is Lord,” and believe in your heart that God raised Him from
the dead, you will be saved.
For it is with your heart that you believe unto righteousness
and it is with your mouth that you confess
your faith and
are saved.
(Romans 10:9-10)
