Overview
Limited to 1,990 watches and honoring SR-71 pilot Brian Shul, the Ball Engineer Hydrocarbon AeroGMT Sled Driver tracks three time zones on a luminous black dial.
A tribute to the SR-71 Blackbird
Retired U.S. Air Force Major Brian Shul was one of only 92 pilots to fly the SR-71 Blackbird. The long-range reconnaissance aircraft flew at high altitude and at speeds above Mach 3, and its crews called it the Sled. The watch pays tribute to both Shul and the Blackbird. Each of the 1,990 pieces made worldwide has a titanium case back.
Three time zones at once
The main hands show local time, and a separate GMT hand indicates the time in a second zone. The same hand, read against the 24-hour scale on the bidirectional sapphire bezel, gives you a third time zone. On a trip with a layover, you can keep home, local, and destination time on one watch.
Lit by 44 tritium tubes
Forty-four sealed tritium tubes light the hands, black dial, and bezel continuously, so all three time zones stay readable after dark. The glass tubes generate their glow from within, so they never need exposure to light.
Protected against magnetism
Protection against magnetism goes back to Webb C. Ball’s rules for railroad watches, drawn up after an 1891 train collision at Kipton, Ohio. The watch withstands magnetic fields up to 4,800 A/m (the international standard for antimagnetic watches), which helps protect the movement’s rate. The case is water-resistant to 100 meters.
The details
The stainless steel case measures 42 mm across and 13.85 mm thick, with an anti-reflective sapphire crystal. A patented crown guard shields the crown and helps ensure it is properly closed. Inside, the COSC-certified Ball RR1201-C automatic movement provides a 42-hour power reserve. COSC is the official Swiss institute that tests chronometers for accuracy over 15 days.
The 21 mm stainless steel bracelet fastens with a patented folding clasp that includes an extension.

Questions & Answers
How do I read the three time zones?
The main hands show local time, and the GMT hand reads a second zone on the fixed 24-hour scale. Turn the bidirectional bezel to read that same GMT hand against another 24-hour scale for a third zone.
Who does the Sled Driver edition honor?
It honors retired U.S. Air Force Major Brian Shul, one of 92 pilots to fly the SR-71 Blackbird. Sled was a nickname for the aircraft, and this edition is limited to 1,990 watches.
How do the travel scales stay illuminated after dark?
The 44 tubes illuminate the hands, hour markers, and sapphire bezel scale, keeping the time-zone readings visible after dark. Inside each sealed glass tube, tritium activates a luminous coating. The tubes glow continuously, without a battery or any need to be charged by sunlight or a lamp. The glow gradually fades as the tritium decays, with a half-life of about 12.3 years.
What does magnetic resistance mean for the movement?
Magnetic fields can disturb a mechanical movement’s rate. Magnetic resistance is rated at 4,800 A/m. Stronger fields can exceed that protection.
What does COSC certification mean for this movement?
The movement passed independent chronometer testing over 15 days, in five positions and at three temperatures. The permitted average daily rate during testing is -4 to +6 seconds. The test is done before the movement is fitted into the case, so the watch’s daily rate on the wrist can vary.
What does the Hydrocarbon crown guard do?
The patented guard protects the crown against impacts and helps ensure that it is properly closed. Both the crown and guard must be secured before the watch is exposed to water.

Iguana Sell had an 18% site-wide discount and this watch in-stock. I did some quick research to see if they were a legitimate retailer, then made the purchase. I received tracking updates and a simple import form for US customs I had to sign, and that was it - very straightforward. I got a great watch at a great price and would happily purchase from Iguana Sell again.

Bought this as I have an emotional attachment to the SR-71 Blackbird aircraft it has emblazoned on it at the six o'clock position. Wears a little large for me, but it's an impressive piece that gets lots of attention. Iguana's service is exceptional too, I get instant replies over WhatsApp and they are even working at getting me another limited edition Ball watch.
You won't regret the purchase.
