[Rolex] What's a good companion to a Speedster Pro and Rolex 1675?

In my use, the 1675 is on Oyster, for daily use. The Speedster on black Omega Use for weekend/casual use. I'm now looking for a 3rd piece, one for grocery runs , around water, and more physical work in sweat pants n such. I wanted another dial color than black if possible, and no blue or red bezels. Priced 200-1000, and lug to lug no larger than a Speedy (53?). Im considering the Sinn 104 in white (once they hit the used market), Seiko Paid Turtle in Black. I want the watch to 'fit' thematically and with the colors/styles of the other watches in mind. Not just get a G Shock. Thoughts?
