Panerai Lab-Id Luminor 1950 Carbotech at SIHH 2017
We all know rubies have been utilised in watchmaking for decades as a means for lubrications — so the fact they are all but redundant here is rather exciting.
Oh, and you also get a 50 year guarantee from Panerai. One final note: 49mm seems large! I get that. But I have to say, having strapped it on today, it sits far smaller. This would be a killer weekend watch should you have the means (price point is circa $50k).
