THE SKINDIVER "WORLDTIMER"

In the early 1960s, Wolbrook and its sister brand Douglas introduced the Skindiver “Worldtimer”: a solid, water-resistant and highly legible timepiece with luminous markers and hands, a bold red sweep second hand, distinctive hour and minute hands, a 24-hours / Military Time scale along with a rotatable bezel with time zones and elapsed time.

This mix of features from a diving watch and a pilot watch makes it the kind of tool-watch a NASA engineer and test pilot would choose and operate.

SKINDIVER WT PROFESSIONAL OVERVIEW

NEIL ARMSTRONG'S TOOL-WATCH

As many pilots, astronauts or regular men and women through the 1960s and 1970s owning a personal, extra back-up watch on top of your standard issued time instrument was common sense and practice.

And for that, Neil Armstrong selected and wielded a readable and efficient timepiece: The Skindiver “Worldtimer”.

Neil's tool-watch was auctioned and authenticated in 2019. By the look of it - wear and tears, faded marking on the bezel, along with a replacement military specs nylon strap - it did not stay in a drawer.

SKINDIVER WT PROFESSIONAL OVERVIEW

THE X-15 HYPERSONIC ROCKET-POWERED AIRCRAFT

At the dawn of the space race, before men looked up to the Moon, the first frontier was outer space. In 1960, to carry on aerodynamic researches, NASA engineers defined the requirements for an ultimate plane: a hypersonic rocket-powered aircraft capable of near space flight. The X-15 program was born.

From 1959 to 1968, through 199 flights reaching the maximum altitude of 107.8 km (67.0 mi) and the top speed of 6,206 km/h (3,856 mph), NASA’s X-15 experimental planes laid the ground work for spacecraft navigation. The 12 test pilots from the program were from the US Air Force and NASA.

Among these audacious and highly skilled pioneers was the man who would set the first foot on the Moon in 1969: Neil Alden Armstrong.

THE TOOL-WATCH OF
A TEST PILOT AND ENGINEER

During his unique career as an engineer, test pilot and astronaut for NASA, Neil Armstrong flew hundreds of high-performance aircrafts and spaceships. In which of these, his Skindiver “Worldtimer” wristwatch was part of the adventure is a mystery.

This is where history stops and the legend starts…

X-15 LIMITED EDITION CASEBACK

The Skindiver WT Professional X-15 Limited Edition celebrates and pays tribute to the X-15 aircraft by featuring an engraving of this incredible plane on its caseback and the iconic aeronautical industry line:

SKINDIVER WT PROFESSIONAL OVERVIEW

SHOCK RESISTANCE
A STEP AHEAD

The newly engineered HexapleX® watch case architecture brings enhanced shock-resistance via the use of “3D” rubber shock absorbers strategically placed in the front, back and side of the movement holder.

The movement is subsequently in a “floating” configuration and effectively shielded from big to micro impacts on the watch case.

The result is the most impact resistant and accurate* Skindiver tool-watch Wolbrook has ever manufactured.

*micro-impacts are responsible for loss of accuracy overtime.

HEXAPLEX® WATCH CASE ARCHITECTURE

1. Enhanced Shock-Resistance - Movement shielded by “3D” rubber shock absorbers

2. Screw-Down Winding Crown & Caseback - Superlative sealing from water & dust

3. Water Resistance to 12 ATM / 120m - Tested & guaranteed

4. Mono-Bloc Middle Case - Rigid & durable structure

5. Drilled Lugs - Easy strap changes

6. 316L Stainless Steel Case - Hand finished brushed & polished marine grade stainless steel

• Quick date setting

In-house modifications and operations:
• Modification of the date disk to a “Roulette” style disk with the date in black on odd days and red on even ones
• Control and setting with a tolerance of ±15 seconds and a beat error of 0.6ms

HESALITE GLASS: THE PRO’S CHOICE

From the 1960s and earlier, armed forces around the world along with NASA issued wrist-watches secured with Hesalite glasses to service men, pilots and astronauts. Why? Hesalite offers high transparency, strong impact resistance and do not shatter like glass or sapphire would.

To this day, above or under the ocean, in a cockpit, or even in space, the possibility of having tiny bits of glass floating around or having the face of the watch exposed to the elements is considered an unnecessary risk and a direct threat to mission success.

TIME ZONES
TRACKING FUNCTION

On the bezel, the “+” and “-” in front of the cities allow you to define if these cities are before or after Greenwich, and if you need to read a time difference clockwise or anti-clockwise. Between “Greenwich” and “+Tokyo”, you have a time difference of +9 hours and between “Greenwich” and “-Denver” you have a time difference of -7 hours.
Let’s say you are in Sebring, Florida, USA and you want the time in Le Mans, France.
1. Sebring follows the Eastern Time Zone / UTC-05:00 (defined by “-New York” on the bezel), then you need to rotate the bezel and put "-New York" on the hour marker just passed by the hour hand. If it's 12:30 in Sebring. Then you place "-New York" on the 12:00 marker.
2. Le Mans follows Paris time zone / UTC+01:00. Paris is a forward time zone (there is a little “+” in front), you read the bezel clockwise and you see that it indicates 18:00. So, it's 18:30 in Paris and Le Mans.
