Apologies, my original message stated white dial, I think it is actually a silver dial.

The two I’m looking at are:

This conversation is now unintentionally overlapping slightly with another thread of mine, but I want to share some examples of watches I have tried on here purely from a size point of view.

I'd be interested to hear if the forum thinks any are too small or too large.

Aqua Terra - 38mm

Aqua Terra - Black 41mm

De Ville - 40mm

Grand Seiko - 37.3mm

Nomos -38mm?

Nomos Neomatik - 41mm?

Nomos Zurich - 40mm?

I have now also tried on a Grand Seiko 😍

I think it's my favourite dial/look of them all, but it is quite thick.

37.3mm

My wrist size is 18.1cm. 

as I say in my latest reply, I’m not sure what watch size people typically recommend for different wrist sizes?

Thank you for all the comments and recommendations so far. I appreciate the guidance.

I have gone and tried some watches on today. I've attached some photos below.

I have a question about sizing. My wrist size is 18.1cm. What watch size would people typically recommend for this?

I really like the Omega Aqua Terra. I tried this in both the 38mm and 41mm sizes, and I am unsure which I preferred, I think I am leaning towards 38mm.

I think the Aqua Terra blue face was my favourite.

I also tried the Omega De Ville Tresor in 40mm. Which I really liked 😍 But I do wonder if it's marginally too big.

I also tried on some Nomos watches. My local dealer is currently doing 25% off on them, so this is an interesting proposition.

I like the Nomos, but I worry that they are not a classic design and that I am more likely to get bored with them faster than I would the Omegas.

Aqua Terra - Blue 38mm

Aqua Terra - Black 41mm

Aqua Terra - Black 38mm

De Ville - 40mm

Neomatik - 41mm?

Zurich - 40mm?

Orion 38mm?

I am a big fan of the Aqua Terra in Blue, but I worry a bit about how well it will wear with a suit.

Do ADs really move on price to get a deal? I had, perhaps ignorantly, assumed that the list price was the final price.

When I look at the Grand Seiko website in my budget the SGBW285 doesn't come up.

The main options I am seeing are the SGBW285, SGBW253, SGBW257, SGBW255.
