I think that one contains a (possibly) modified Sellita SW300. I like the look of it but it would need to be bought at a huge discount unless it’s a keeper. The usual US dealers often have montblancs at 70% off. I almost went for an 18k version of the linked watch recently. Xupes have one unworn for just over £4k, but it was only £2k in their January sale, and didn’t sell at that price.
I’m not sure what’s happened to Montblanc recently. They were making big noises a couple of years ago about expanding their watchmaking efforts, even going as far as buying Minerva. Many commentators were tipping them as the next big player but things don’t seem to have developed as intended. Maybe they just couldn’t shake the image of being a pen maker that just dabbled in watches. A shame really as the build quality of their watches is very good.
