In 1969, Seiko released the world’s first automatic chronograph equipped with both vertical clutch and column wheel, known as the Seiko Speedtimer. One piece from the first 6139 Speedtimer series, rose to stardom as the first automatic chronograph to travel in space: in the 70s, NASA astronaut Colonel William Pogue took the original chronograph on a mission to Skylab – the first US space station. The watch became nicknamed the ‘Pogue’ after its star explorer wearer.
Under a curved sapphire crystal glass is a vivid yellow dial, characteristic of the 6139 original, the second hand, and subdial minute hand at 6 o’clock are in a bright red. With 12 spots of Lumibrite across each of the wide vintage-style indices, this Speedtimer is designed for legibility in dark conditions. In the style of the original, this piece has a blue and red aluminium bezel with a tachymeter feature and a chronometer second scale on the inside dial ring. The bracelet is tapered from the lugs all the way to the buckle.
This modern version features a V192 solar chronograph calibre which charges in both natural and artificial light. Accurate to +/- 15 seconds per month, it has a power reserve of 6 months at full charge.
Prospex timepieces are practical, reliable and durable within extreme or everyday environments, for sports lovers and adventure seekers alike. Seiko 2 Year Guarantee.
Jewellery Odyssey:
Seiko began as a clock repair store in Tokyo in 1881, founded by the current CEO’s Great grandfather, the name derived from ‘Seikosha’ or ‘House of precision'. With a purpose to pursue watchmaking excellence, Seiko has grown into a global timekeeping presence. Renowned for horological innovation with a stream of world firsts including the first TV watches, Seiko created the first ever quartz watch in 1969. Seiko timepieces deliver precisely beautiful Japanese aesthetics, brought to life through total in-house manufacture.

We will provide alterations on the same day, generally the waiting time for this service is 30 minutes.
General Watch Care:
Avoid direct contact with: fragrances, lotions, cosmetics, skincare, hairspray, detergents, solvents / other chemicals. Avoid damaging the movement by sudden impact or shock. Vibrations to the movement can be caused when participating in physical activities such as by playing sports (eg: tennis, golf…).
Avoid extreme temperature changes (saunas). For mechanical watches, avoid prolonged exposure to magnetism, as it can cause minor interference or if exposed to stronger sources, it can stop the watch. To prevent scratches, avoid wearing a bracelet on the same wrist.
Water Resistance:
Many watches are labelled as “water resistant”, this means that it is only humidity protected. So, whilst it can withstand accidental splashes (rain/washing your hands), it is not suitable to be submerged in water (shower/swimming). Atmospheres and Bars are used to measure the amount of pressure (not depth!) a watch can withstand. Water Resistance cannot be constantly nor permanently guaranteed. It may be affected by many factors such as aging of the gaskets or deformation of watch parts, due to accidental shock. Over time the water resistance level will drop. Exposure to hot water conditions (such as: baths, showers, saunas), chlorinated swimming pools or salt water will cause corrosion and wear and tear of parts. Therefore depending on your lifestyle, many watch connoisseur's will advice on testing your watch yearly.
Setting The Date:
The internal movement of either a quartz or mechanical watch, requires more power and energy to change the date, than it uses to move the hands. The movement accumulates power, before and after midnight, in order to move the date change mechanism. To avoid causing damage to this mechanism, never adjust the date between 9:00 pm and 3:00 am, as the adjustment period is already set in motion.
Stainless Steel:
Stainless Steel is hypoallergenic, it is an alloy of iron, chromium, carbon, nickel and titanium. It will not rust, oxidise, corrode or tarnish - if the protective surface layer of chromium, is maintained and not damaged. Hence, it is important to avoid abrasive chemicals (as these can also cause staining) such as: tooth paste, detergents, bleach, chlorine, salt water etc… If it is constantly exposed to environments, whereby these chemicals or elements are prevalent, then it will be prone to develop rust and you will begin to see discolouration and tarnishing. Stainless Steel is easily scratched and dented, so it is important to be mindful of sharp objects when wearing or storing. Clean using warm mild-soapy water, rinse and dry with a soft cloth. Or, gently rub parallel to the direction of the grain, using a microfibre cloth.
