ONLY ONE?
If I can only nominate one, then this is it: Seiko Samurai titanium case blue dial, shark strap

Light weight, great visibility

Interesting case shape and easy-to-operate crown

Traditional 7S25 automatic movement

Substantial presence without unnecessary frills or weight

I've had it for 15 years and have had NO problems at all
If you wanted my top in gold, in quartz, in Spring Drive, in manual wind, in skeletonized -- I've got them. But this is Number One today.
