Pelagos has more modern design sensibilities, whereas the BB is more classically designed to harken back to 50s-era dive watches. Both are different enough that seeing both in a collection doesn't seem excessive, to me. :)
Dang that Hanhart is beautiful. Wish we could go high enough in the price-point for the Breitling Top Time as I love that watch (though, I was able to buy him a pre-owned Breitling Premier for his 70th birthday - so he's at least got that end of luxury covered).
