FS: Summer Topper Special on Seiko JDM Prospex Models SBDX013, SBDC047, SBDB011 and more

When it comes to Seiko, nothing in the brand's portfolio says 'summer' quite like its Prospex collection. Short for "Professional Specifications," watches in the Prospex line have been tailor-made for summer adventure, with high marks for legibility, durability, water resistance, and all-around capability for whatever you have in store this season – whether you're exploring new beaches and high mountain peaks, or just reaching for another margarita while poolside.

This summer, we're proud to offer a handpicked selection of Prospex watches, previously only available in Japan, but available exclusively at Topper, each for a very special 30% discount and in very limited numbers. All watches are brand new and come with the full manufacturer's warranty from Seiko. Shop the sale right here.

Here's what we have, fresh on arrival from Japan:

Seiko SBBN029 Marinemaster Tuna

Appropriately leading the sale is a very special Limited Edition Tuna, built to commemorate the 50th Anniversary of Seiko's first dive watch – the godfather of the Prospex collection, which made its debut in 1965. Water resistant to a staggering 1000 meters, this particular Tuna exhibits a titanium case with ceramic shroud, and is fitted with Seiko's in-house produced 7C46 quartz movement (accurate to +/- 5 seconds per month), which was engineered specifically to meet the exacting needs of the deep-diving Tuna watches. Shop this watch here.

 

Seiko SBDX013 Marinemaster "Darth" Tuna

Though encased in the same titanium and ceramic armor, the Seiko SBDX013 Marinemaster Tuna differs slightly from its limited-edition commemorative cousin above in color and movement. With its sinister all-black case and shroud, and Seiko's 8L35 in-house manufactured movement, the SBDX013 "Darth Tuna" enjoys cult status amongst watch fans as the deepest-diving automatic Tuna in the sea, and we wouldn't have it any other way. Shop this watch here.

Seiko Prospex SBDC047 Transocean

Introduced in 2016 as a slightly stylish, more modern alternative to the traditional Prospex divers, the ISO-certified Transocean has remained one of the collection's most underrated, and visually distinct options. This 6R15 automatic movement-equipped watch exhibits some of the Prospex line's most interesting case and dial work – with a beautiful center-gradiant blue dial, interesting facets and angles, and a Dia Shield-finished bracelet that flows uninterrupted from case to clasp, in very Genta-esque fashion. It also marked the first time that Seiko equipped a Prospex dive watch with a full ceramic bezel and sapphire crystal. And with a modern 45mm case width, but only a 45mm lug-to-lug measurement, it wears comfortably on a wide variety of wrists. Shop this watch here

Seiko Prospex SBDC037 Transocean

Just like its blue-dialed cousin, the SBDC037 exhibits a rich feature set and modernity at every angle, on full display here with a boldly textured white dial and PVD-coated rose gold accents in the caseband, hands, and applied dial elements. In addition to the same Dia Shield-finished case and H-Link bracelet, key design signatures of the Transocean line persist, namely the beautiful dial depth and contrast here, with the thick, ceramic bezel (now white) leading to the applied hour markers set into a deeply sloped chapter ring. Nothing says 'summer' quite like a white-dialed dive watch, and given their relatively uncommon nature, this is a very cool one indeed. Shop this watch here.

Seiko Prospex SSF001 Marinemaster GPS Solar

The Seiko Prospex SSF001 Marinemaster GPS Solar is a true mariner's watch – designed to remain legible and survive harsh environments, while maintaining extreme, fully automated precision anywhere in the world. SSF001 is essentially a waterman's Astron, which you might recall is built with a titanium case around Seiko's proprietary GPS Solar 8X53 caliber, which displays a second time zone at 6:00 in 12-hour format, and then houses an AM/PM indicator at 2:00. More importantly though, the movement also synchronizes with GPS satellites to triangulate your current position – and can jump the hands to the correct local time at the push of a button. This is made possible, thanks to a GPS antenna ring, which is hidden beneath the two-piece blue and white ceramic bezel, engraved with each of the GMT timezones. The SSF001 Marinemaster is limited to 1500 pieces, and we're quite pleased to have received a small number exclusively for this summer offer. Shop this watch here.

Seiko Prospex SBDB011 Marinemaster 600m Spring Drive Diver

The SBDB011 is the 'one Prospex to rule them all,' and arguably the apex of over 50 years of dive watch know-how. Crafted in a 46mm Dia Shield-coated titanium case, with an aggressive 'buzz-saw' rotating bezel and ingenious screw-locked bracelet, it's easily one of the most striking Prospex watches Seiko has ever offered. Inside, the SBDB0011 is powered by Seiko's 5R66 Spring Drive movement – a sophisticated GMT caliber produced at Grand Seiko's Shinshu Watch Studio, which is noteworthy for its independently adjustable hour hand, +/- 15 seconds-per-month accuracy, and generous three-day (72-hour) power reserve. There are few watches that straddle such a fine line between traditional design codes, and ultra-modern capability, and the SBDB011 is absolutely one of them. Shop this watch here.
