I have two modes. Professionally, if you're not early you're late. Personally, I'm always fashionably late.

I would not sell a speedy for a Seamaster. Unless you do t have another solid diver.

However, the SMP 300 on the wrist is stunning. It makes a statement much more than the speed master. The white face just pops in a way that the speedy cannot.

I am on the fence right now. May revisit the Cartier boutique around Thanksgiving.

What are your thoughts on the fit? I typically have to have micro adjustments on the fly. I'm wondering if the weight/thickness of the watch make that less necessary. 

Love the pairing with your precision plinker. 

Same for me actually. I have friends in the Northwest that love the brand. I can't really get excited about any of them. Also IWC. 

A hard decision for me. I rotate watches often during the week and I have a fondness for many pieces. When I think about longevity and wearability, the Submariner comes to mind but I can't see my 70yr old self sporting a tank of a watch like that. After much contemplation I arrived at my accomplishment watch. The Yachtmaster 40.

You didn't give us a lot to go on. The Zenith is a bit larger watch - so wrist size will matter. If you have a 1 watch collection the airking may be more versatile. Ultimately, if you are not attached to the airking then make the trade -- that model being left in a box is not going to greatly appreciate. Get what you want.

Can you add pics in a reply? Sorry new to the site.

I did post my 300m on the daily what are you wearing post.
