I think the Explorer II 16570 is criminally underrated.
It sits in a sweet spot where it’s modern enough to be considered a durable daily, but still has everything I like about the older five digit sports watches. 40mm case, steel bezel, relatively slim proportions and none of the bulk of the generations that followed.
This one is particularly interesting because it’s a 2008 example fitted with the later calibre 3186. You get the blue Parachrom hairspring and the revised hour setting mechanism, while keeping the classic proportions of the 16570.
The condition is also seriously strong. The case still has really well defined proportions, with crisp lugs and crown guards, while the brushed and polished surfaces remain nicely separated. The fixed steel bezel is good, with sharp engraved numerals and only very light signs of use.
The original black dial is clean, with crisp printing, well-preserved luminous plots and matching hands. The 78790 Oyster bracelet also presents beautifully and ties the whole watch together.
For all you full set collectors it ticks that box as well. Original inner and outer boxes, warranty card, serial swing tag, wallet, booklets.
A late 16570, the right movement, excellent condition and a complete set.
Exactly why I think these deserve far more attention than they get.
