Well in my opinion if this was a watch without a dive bezel i would say go 39.5mm but since this does have one i would say 43.5mm since dive watches have smaller dials and it will give the illusion of the watch being smaller than the size suggests. Also if i remember correctly the Aquis doesn't have a long lug to lug distance.

Worst case scenario is you might have to exchange it or return it if you don't like the fit. Just keep all the tags and plastic on it until you know for sure.

Nice choice btw.

 

Thanks mate.

I've never actually seen the watch in real life however I've heard plenty of comments how the watch looks chunky. That's the reason I was thinking of the smaller size.

 

For 17cm wrist I recommend 43.5 mm, and yes that’s what I have and mine is 16.5 cm.

Aquis has short lug so it does not wear big.

 

Sorry guys, just measured my wrist again and it's actually 16.5cm. Do you still suggest 43.5mm?

 

39.5, no doubt. Even more given you are not going to test it before buying (and even if you tested it, while you might convince yourself you can bear it, and/or even that it looks better, it is in the long run that you would start thinking "is it not a bit bulky/heavy?"). You can't go wrong with the shorter one, while you can (and IMHO, you certainly will) with the larger one.

Even if you can stand the larger watch, it doesn't mean you should, and I have no doubt the shorter one will be more comfortable. And, given its design, "vanilla" round, and with a not too wide bezel, 39.5 becomes a no brainer.

 

Have you Tried the Oris sub sequetion ? there pretty helpfull and freindly folks. thats really a tough call on the size, i have the 43mm aquis and while big, it wears good. I cant speak to the 39.5mm or 43.5mm. Do you like your watches more modest in size ?

 

I'm going to disagree and say for sure the 39.5mm. the Oris is a big watch, despite the lugs. You can probably pull off the 43 if you want a big watch, but if you prefer slightly more moderate size, I'd really consider the 39.5

 

I would go with the 39.5 unless your wrist is 17.5 cm or greater or you really like large watches.

A good rule of thumb for what watch diameters will best fit your wrist is the ratio of your wrist circumference (in mm) to watch diameter should be between 4 and 5. For a 16.5 cm wrist, that works out to sizes between 33mm and 41mm.

 

I have the larger version and a small wrist.....6.75”. The watch does not wear big to me.

 

See my post and photo in the Oris forum.

 

I have a 17.1 cm wrist and had to flip my 43mm to buy the 39.5mm because the first one was just too overwhelming on my wrist, as an FYI.

Good luck.
