I have both on the bracelet.

I strongly dislike the zenith bracelet (feels pretty weak to me and kinda cheap). Also important to note that the dial looks more silver than white so that might throw off the expectation you have of it.

The speedmaster feels good on bracelet, probably my favorite bracelet ive ever had on a watch. And easily more legible.

I think both are good buys and both keep good time. But if youre going no bracelet, maybe the zenith is the way to go. A bit smaller case but still nice looking

Yeah idk, the watch looks cool but i think it has the same movement as the iwc mark xx and my mark xx ends up being almost 3 minutes fast after 3-4 days. My speedmaster and chronomaster original dont go past a minute in that same time frame. Id wait til prices drop in the secondary market

Watches are utility and jewelry to me. I use one when running or when i want to leave my phone behind and do things outside the house without having some device with me.
