Seiko Commemorates the World Athletics Championships with a Limited Edition Purple Speedtimer

The Seiko Prospex Speedtimer is one of those watches that is just incredibly easy to recommend. It runs on a solar powered quartz movement, which makes it ultra practical and reliable. It’s styled to look a little like classic vintage chronographs that we love, but isn’t an on-the-nose recreation of any in particular. And they come in an easy to wear 39mm case, a fairly neutral size for just about any wrist. They’re also relatively affordable, coming in well under $1,000.  Seiko has released several of these “SSC” Speedtimers in recent years in a variety of colorways. The latest is a limited edition for the World Athletics Championships, which this year returns to Tokyo for the first time in 34 years. Seiko has been the official timekeeper of the World Athletics organization since 1987 and has made a number of watches to commemorate the partnership in that time.  This Speedtimer would seem to capitalize on a fairly persistent trend in the watch world: the purple dial. According to Seiko, the tone of this dial in particular is inspired by “Edo purple”, a shade long associated with the city of Tokyo. This color has also been designated as the official color of this year’s World Athletics Championships event.  The purple base is accented with black chronograph subdials and a black tachymeter bezel, along with applied faceted hour markers and lume filled hands that have been outlined in black for increased legibility. The black and purple combination works w...

Introducing – The Vacheron Constantin Métiers d’Art “Tribute to The Celestial” Collection

As one of the most prestigious watch manufactures from Geneva, it’s no surprise to see Vacheron Constantin playing in the field of artisanal crafts, or what the industry names “métiers d’art.” One of the recurring themes used by VC are the zodiac signs, expressed in various manners over the years, either through yearly Chinese-themed watches […]

Vacheron Constantin’s “Tribute to The Celestial” Artfully Blends Gemstones and Guilloché

Continuing with its 250th anniversary special editions in fine style, not long after the Temporis Grand Complication, Vacheron Constantin’s latest is the 12-piece-strong Métiers d’Art “Tribute to The Celestial”. Each watch is dedicated to symbol of the zodiac, with the respective constellation rendered in hand guilloché on the dial, while the case is set with baguette-cut sapphires totalling almost 4 ct. Fortunately available individually instead of only as a set, each “Tribute to The Celestial” watch is powered by the cal. 2160, an automatic movement with a tourbillon and novel peripheral winding mechanism. Initial thoughts Vacheron Constantin (VC) has long combined complications and gemstones, though in a relatively low-key manner since such watches were rarely announced publicly. The series of Overseas Perpetual Calendars set with coloured stones, for example, was never widely publicised. The “Tribute to The Celestial” demonstrates what VC can do with its in-house guilloche workshop and gem setting (which is probably not done in house). The watches are striking and beautiful, though certainly only for fans of blue, and only blue. Despite the gemstones and guilloche, the watches look surprisingly modern, likely due to the colour as well as the geometric nature of the engine turning. Though the guilloche is done the old school way on a hand-operated machine, the engraved zodiac symbols look nothing like traditional guilloche. Not all the zodiac emblems a...

Ian Skellern has been a Greubel Forsey fan boy since the brand launched back in 2004, but his appreciation for the brand’s beautifully executed complications was always purely platonic. It wasn't just the price, their watches were too big for him. The sub-40 mm Balancier Contemporain changed that and this blue stainless steel final edition looks sensational!

eBay Finds: A Fun Digital Seiko from the Year Star Wars Premiered, a Hamilton with a Unique History, and a Zodiac Sea Wolf in Great Condition

eBay Finds is back! This bi-monthly installment will feature a selection of watches currently listed on eBay that have caught the eye of editor Christoph McNeil (@vintagediver). If you come across any hidden gems on the ‘Bay drop us a note at info@wornandwound.com for potential inclusion. Vintage Zodiac Sea Wolf  The Zodiac Sea Wolf is an absolute icon in the vintage dive watch world, and this early metal bezel version is a nice example. There were many iterations of the Sea Wolf, with various bezel materials, dial colors and date/no date versions. This black dial, date with metal bezel is an earlier combination, and definitely sought after. The plated bezel is usually pretty worn, and the lume can be degraded or re-done on these. This example has a nice clean black dial with great lume on the dial and hands, and the bezel is in top shape. The crown is also original and signed with the Zodiac logo as it should. No movement pictures but the seller states the watch runs well.  View auction here Vintage 1970s Bulova Jet Star  Here’s a wild vintage Bulova from 1974, that looks every bit the 70s watch. The 40mm gold plated UFO style case is excellent and unpolished, still showing the original radial brushed finish. The case may draw your eye, but it’s the bold two-tone orange dial that keeps you looking! The dial is a bright orange that turns darker at the outer edge. Applied markers outlined in brighter orange and steel and white hands with a day-date window at 3 o’...
