Have you considered an analog clock with a sweep second hand, positioned where your room safelight illuminates it?
I have one of these, with 2 layers of rubylith covering the display. Then I have a pice of black foam core hinged to the top to cover it when I need total darkness. Works just fine.
This is what I am doing but my eyes are aging faster than the safelights which are dim.

I do have a Atomic Clock but the 80 year old walls in my house protect it from the pesky time setting radio waves.
The Rubylith ensures whatever the wavelength of light given off by the numerals becomes safe - I think.
Is the Apple Watch "red/orange" pure red, and is that a B&W paper-safe red? I'd assume that the Apple watch uses a basic OLED, which means r+g+b, and you'd want to make sure none of the g and b is mixed in with the r.Apple watch, put the dial on red/orange. Or iPhone
I am looking for a darkroom clock, about 7-10 inches in size, that tells time in the usual hours, minutes and seconds and is visible in the dark as a safelight red and can be turned to dim and off without turning off the timing function.
Please and thank you

Exactly what I have to tell time with. For timing processes I have a host of other timers.Have you considered an analog clock with a sweep second hand, positioned where your room safelight illuminates it?

Quite right but I also load large format film in the darkroom and need to turn the red off.Yes, thanks I hadn't noticed that you had specified that it has to be visible in the dark so presumably has luminous numbers including the second hand for say print developing time. Just speculation on my part but if the face is facing out and not down and you don;t have to pass the paper close in front of the face then I'd have thought that the strength of the clock numerals@ luminosity would have been insufficient to affect the paper
