Reference:216570: Difference between revisions

The half-orange 24-hour hand is the visible historical citation. The original 1655 Freccione carried a fully orange arrow-tipped 24-hour hand, dropped from the 16550 and 16570 in favour of a red baton. The 216570 brings orange back, now as a black-and-orange split: black on the inner half closest to the centre, orange on the outer half that does the actual reading against the bezel. The choice reads as a deliberate nod to the 1655 rather than a styling coincidence, though no launch-era editorial coverage spells out the intent directly.

The part of the run worth tracking is its ending. Rolex kept the 216570 in active production through the early part of 2021 while the 226570 was announced and rolled out alongside it, the same overlapping-window pattern the 16570 had with the 216570 at its own end. Sotheby's catalog descriptions occasionally date 216570 examples to "circa 2010" — those reflect catalog dating rather than a true pre-2011 delivery, since the Baselworld 2011 launch is the documented start.

Caliber 3187 powered the 216570 across the full run. It is a 28,800 vph automatic with 31 jewels, 48-hour power reserve, hacking seconds, an independently-setting local hour hand, and quickset date. Mechanically the 3187 is an evolution of the 16570's late 3186: the same general architecture, with an enlarged base plate to fit the wider 42mm case, the addition of Paraflex shock absorbers, and the blue Parachrom hairspring with Breguet overcoil that Rolex had been rolling out across the sport line. James Robinson's 2020 Time+Tide review gives the rate as -2 / +2 seconds per day, which is Rolex's Superlative Chronometer figure for the period rather than the tighter post-2015 in-house specification.

The case measures 42mm in 904L Oystersteel, about 12.5mm thick and about 49mm from lug to lug. The case wears as a sport Rolex of its generation rather than as a scaled-up 16570; the lugs are wider, the crown guards larger, and the overall mass higher. There are no lug holes — the 216570 launched with the no-holes case the 16570 had transitioned to in its V4 era. The watch is rated to 100m, the same depth rating the Explorer II has carried since the 16550.

The bracelet is Oyster construction in 904L Oystersteel, centre links vertically brushed, flanks polished to a mirror finish. The bracelet width at the lugs is 21mm — the 226570 widens this to 22mm in 2021, one of the more visible generational tells. Solid links throughout. The bracelet reference number is variously cited as 78390 or 78390B across dealer copy and forum threads; published editorial coverage and Sotheby's lot descriptions describe the bracelet by construction rather than by reference number.

The clasp is the Oysterlock folding clasp with a flip-down Easylink comfort extension that adds approximately 5mm of length without tools. Easylink is a binary in-or-out extension rather than the continuous Glidelock micro-adjustment Rolex had introduced on the modern Submariner. The 216570 never received Glidelock — neither did the 226570. That puts the Explorer II line at a different bracelet generation than the contemporary Submariner 116610LN and GMT-Master II 116710BLNR, which had moved on. Clasp date codes mark the bracelet's production date, not the watch head's, per the standard clasp-code rule.

The 216570 shipped in the standard Rolex green-and-white box of the 2010s, with COSC certificate, white plastic warranty card, booklets, and hang tags. The warranty card format Rolex used through the 216570's run is the credit-card-style white card that had replaced the older paper card in 2006. The packaging is period-correct rather than reference-specific; the same box and card configuration shipped with every steel sport Rolex of the same window.

A small number of 216570 examples have circulated with aftermarket black PVD coating applied by retailers rather than Rolex. Rolex never offered the coating and does not endorse it. Watches with original surfaces command a premium over PVD-coated examples on the secondary market, and any 216570 listed with a "black PVD" or "DLC" surface should be read as a retailer modification rather than a Rolex variant.

The 216570 trades as a recent-discontinued sport Rolex rather than as a vintage collector reference. Standard examples sit in the high four to low five figures at major-house auctions; military branches sit well above that.
