W-800H if you're OK with a little de-soldering: https://ianrrees.github.io/2019/09/13/casio-w-800h-extras.ht...

Casio's Waveceptor has a countdown timer and syncs to atomic time. I've used them for probably the last 20 years.

The Casio B640.

I love the G-Shock squares if you want to stay with casio. The solar charging one that syncs to atomic time automatically runs about $90 (Model: GWM5610-1). The battery powered, manually set time runs about $40 (Model: DW5600E-1V). They keep such good time, and the batteries last for over 5 years in most cases, and can swap out in a few minutes for a few bucks, that you'll have to decide if it's worth it.

I also like pretty much all Timex Ironman watches... T53151 is small like the F-91W and pretty cheap, usually under $25. The Transit series is more square and modern looking, the TW5M19300 runs under $40.
