Recently I have bought a Mark XVI Spitfire from 2006 and noticed the lug bezels are not polished. It does not bother me but wanted to find out about this deviation from the norm. From all the pictures and videos on YouTube about the Mark XVI Spitfire I have concluded that the lug bevels were normally polished. Only the Mark XV Spitfire (the earlier model) has unpolished lug bevels. What is your opinion on that? Was there a time when IWC released early models of the Mark XVI Spitfire (maybe made 2005 but sold 2006) which had unpolished lug bevels? Or is it possible that this polishing wears off after 15 years? At least the polishing on the case bezel (the one close to the crystal) is still intact and not worn off.
And here is an example of the same watch on the blog lugsandlume.com/the-iwc-mark-xvi-spitfire-one-of-the-more-unique-fliegers-out-there/
You can clearly see the polished lug bevels.
Aesthetically I find the unpolished lug bevels nicer and more casual looking / less of a dress watch look which I like more. But I'm interested in the historicity of this decoration.
