Hi folks

Just want to double check on the C65 Dune Automatic in black - does it have anti-reflective sapphire (any blue tint, therein)?

Not listed on the specs I can see on the CW website. I bought the Sandhurst Series 1 in the clearance, but had to return it due to small defect on the bezel. CW honoured their customer commitments and refunded me in full (hats off to them for dealing with this swiftly and with good email communication).

The Sandhurst did have that anti-reflective treatment, so just want to check on the C65 status. I have checked through some threads, but could not find reference to this, so I apologise in advance if I may have missed something.

...it does say 'Glass Box Sapphire' on the spec area, but no mention of anti-reflective I can see. This may stop me pulling the trigger on one if none is applied...

Apologies if I have missed something about the anti-reflective on the posts I have read. Any help, lads and lassies, very much appreciated...

Hi, sorry that you haven’t had an answer to your question yet. It is weird that AR isn’t often mentioned in specs - for CW or anyone else. As far as I’m aware CW apply AR coating on the inside only. The C11 range had both as I recall, but that was unusual.
I didn’t post this before because I just can’t be definite, and I always figure that someone else will come along who knows more than me!

Many thanks...I've got two Hammy Khakis and the lack of any AR is annoying. I would expect CW to do the inner on most pieces, but a bit strange that some CW specs for certain watches say "inner AR coating", and others (the Dune auto) just say Box Glass Sapphire. So, wary of getting another reflecto. The black Dune auto looks fantastic in pics and on a YouTube vid (WatchChris I think)...and looks like it appears to have the inner anti-reflective.......but would like to know for certain. Thanks for getting back to me, much appreciated.

That’s the same reason I held off on commenting


As far as I’m aware, all CWs these days have AR coating on the inside of the crystal. I don’t know that for certain, but I’m north of 90% sure.

Cheers ajax87....I will await any other replies (owners of the Dune, perchance), or try CW direct to clarify. It's a bit of a stumper, for sure....

I have the white sand dune auto (which makes my ignorance even worse ) - it absolutely appears to have AR coating, though that’s still not a definite answer for you

I’m wondering whether this might be a little bit like automotive features that were once touted in adverts but are now taken for granted: ABS, internally adjustable door mirrors, electric windows, remote central locking and so on. It’s there but it’s not necessarily a selling point anymore? Unless it is, of course…

That’s a good analogy. I was wondering the same thing. Is AR coating simply a given now on a certain level of watch and not worth mentioning?

Thanks guys......not sure about the given/taken for granted bit though. Most (including me) moan about the lack of AR across the Hamilton Khaki range. My Mechanical and Auto (both domed) are awful for legibility in some environments. The Sandhurst Series 1 I had briefly, appeared to have it (the tell-tale blue tinge to the outer edge of the crystal) - see attached pic from another owner I sourced online (top of crystal has that bluish hint -which I like!). I can't see any pics posted online that indicate this in a similar fashion on the Dune, so was hoping a Dune owner could confirm in some way?....I have emailed CW for clarification to hopefully get some feedback.

Let us know what you hear!

This just in from my email to Customer Services re the Dune....

Hi Ross,
I can confirm we do have an AR coating on the inside of the sapphire crystal, please let us know if you need anything else.

Kind regards,
