Seiko’s Advanced Astron Collection Gets Four New References Worn & Wound

Seiko’s Advanced Astron Collection Gets Four New References

If you like your watches complicated and your timezones varied, chances are you’re already aware of the Seiko Astron GPS Solar line, first launched in 2012. No, the watch doesn’t shout haphazard driving directions at you. Instead, its latest models use GPS technology and a solar-sensitive dial to automatically update the time according to your geographic position up to twice a day. But Seiko wasn’t done there-almost exactly a year on from the introduction of the Caliber 5X83, the first pairing of Dual-Time tech with a chronograph function, Seiko has unleashed four new Astron GPS Solar Dual-Time Chronographs. Each of the four new watches-references SSH175, SSH177, SSH179 and limited-edition SSH180-features a titanium bezel with a sapphire crystal insert, adding a touch of practicality and elegance to the already robust profile of the Astron. An imposing 44mm mirror-polished titanium case houses the Caliber 5X83 movement, which promises a litany of advanced features, most prominent of which is the aforementioned GPS-controlled time and time zone adjustment. A world time function, perpetual calendar correct to the year 2100, automatic DST adjustment, AM/PM and signal reception indications, accuracy of +/- 15 seconds per month, and more round out the slate of functions. Of course, the titular chronographs also loom large on the dial, with a 1/20th second counter at 12 o’clock and a 12-hour counter with hours and minutes at 6 o’clock during chronograph operation...

Seiko Refines the Astron GPS Solar Dual-Time Chronograph SJX Watches

Seiko Refines the Astron GPS Solar Dual-Time Chronograph

One of the flagship high-tech analogue watches in Seiko’s catalogue, the Astron GPS Solar Dual-Time Chronograph has been reworked to give it visual elements more typically associated with Seiko’s higher-end mechanical watches. Amongst other things, the new Astron GPS chronograph features a sapphire-covered bezel, diamond-milled chapter rings, and facetted case details. It still retains the multi-function 5X83 movement that features GPS time- and time zone setting, perpetual calendar, and a six month power reserve on a full charge. Initial thoughts Someone recently asked me to recommend a useful watch for a person who has no interest in mechanical timepieces, with the condition that the watch has to be analogue and not look like a gadget. The Astron GPS chronograph fits the bill. The model’s newest iterations, four in all, have the styling details of a mechanical watch while having a multitude of high-tech features. One of its most useful features is the GPS time setting, which means the watch syncs with a GPS satellite and then displays the local time zone when travelling. The black and blue dial versions are especially restrained and well suited as a low-key everyday watch, though still a little large at over 44 mm in diameter. Useful watchmaking When sunlight is detected, the Astron GPS chronograph syncs with a GPS satellite automatically up to twice a day, while manual syncing can be done via a pusher in the case. Sunlight also powers the watch – under the dial ...

Breitling’s Flagship Navitimer B19 Perpetual Calendar Chronograph in Steel SJX Watches

Breitling’s Flagship Navitimer B19 Perpetual Calendar Chronograph in Steel

The flagship watch of Breitling’s best-known watch, the Navitimer B19 Perpetual Calendar Chronograph is now more affordable. The latest iteration with an “ice blue” dial retains the specs of the pink gold 140th anniversary edition launched last year, but trades precious metal for steel. Unlike last year’s limited edition, the new steel model is regular production and is priced under US$30,000, over Breitling’s traditional sweet spot on the price spectrum but still half the retail of the anniversary edition. Breitling Navitimer B19 Chronograph 43 Perpetual Calendar_Ref. PB1920251C1P1_RGB Initial thoughts The new Navitimer B19 keeps it affordable, relatively speaking, by combining Breitling’s excellent in-house B01 movement with the tried-and-tested Dubois Depraz perpetual calendar module. The resulting watch is thick at almost 15 mm high, but combines several complications in Breitling’s iconic slide-rule pilot’s chronograph. While the watch is pricier than most of Breitling’s offerings, it is one of the few perpetual calendar chronographs in this price range. Most of such watches tend to be a lot more expensive, although Austrian independent watchmaker Habring² offers similar for less in keeping with its focus on affordable complications. Value proposition The new B19 retains the same basic specs as its precious metal counterpart. The stainless steel case measures 43 mm in diameter and 14.94 mm in thickness. Water-resistant to 30 m, it features the Navit...

Unique Code 11.59 Grande Sonnerie Editions for Audemars Piguet’s 150th SJX Watches

Unique Code 11.59 Grande Sonnerie Editions for Audemars Piguet’s 150th

The centrepiece of Audemars Piguet’s 150th anniversary is the ingenious perpetual calendar cal. 7138 (at least for now), but the most complicated of the commemorative editions is the Code 11.59 by Audemars Piguet Grande Sonnerie Carillon Supersonnerie. The anniversary line-up of striking watches is comprised of five unique grande sonnerie wristwatches: three have sapphire dials that reveal the intricate strikework, while the remaining pair are fitted with iridescent opal dials. The harlequin opal dial Initial thoughts Though criticised at launch, the Code 11.59 has evolved into a varied range of watches, some of which are notably appealing (some are still pretty boring unfortunately). The grande sonnerie falls into the appealing category. The mechanics of the grande sonnerie are exceptionally complicated, and because it is a Supersonnerie equipped with AP’s patented amplification construction, the grande sonnerie is incredibly loud. The volume of the chimes are loud, but not so much that they are harsh. In short, the acoustics are impressive. The sapphire dial in sand gold case The anniversary edition grande sonnerie are individually appealing, though the opal dials are more interesting due to the novelty of the material. That said, the grande sonnerie can be customised, so a buyer is not necessarily limited to the options available for the anniversary. If I wanted to spend this much on a grande sonnerie, I’d work on my own. The pinnacle of striking watches AP is one...

First Look: Audemars Piguet Royal Oak Perpetual Calendar “150th Anniversary” Openworked SJX Watches

First Look: Audemars Piguet Royal Oak Perpetual Calendar “150th Anniversary” Openworked

Audemars Piguet’s 150th anniversary debuts are centred on perpetual calendars (at least for now), marking the closing of one chapter and the opening of another. The ingenious new calibre 7138 perpetual calendar marks a definitive new chapter in the brand’s history, while the Royal Oak Perpetual Calendar “150th Anniversary” Openworked is the swan song for a storied cal. 2120 movement that Audemars Piguet (AP) has relied on for decades. Presented in titanium with a polished BMG bezel, the final edition perpetual calendar is inspired by the Royal Oak pocket watch ref. 25729. This pocket watch lends its sapphire-and-blue aesthetic to the anniversary perpetual calendar, although the pocket watch was ironically powered by a manual wind calibre (as pocket watches tend to be). The ref. 25729PT was a 20-piece limited edition with a matching platinum chain, made in 1992 for the 20th anniversary of the Royal Oak Initial thoughts The anniversary edition marks the end of the cal. 5134/5135 (and the preceding cal. 2120/2800), the long-lived perpetual calendar movement that AP launched in 1978. While great in its time, the movement was dated and somewhat low-tech by modern standards. The retirement of the movement is well deserved, and it is certainly going out in style. At a distance the anniversary perpetual calendar is familiar, but up close it reveals details that make it a little bit more interesting than its peers. These include the blue ringed-sapphire dial, retro signatu...

Explained: Audemars Piguet’s Revolutionary Perpetual Calendar Cal. 7138 SJX Watches

Explained: Audemars Piguet’s Revolutionary Perpetual Calendar Cal. 7138

Audemars Piguet kicks off its 150th anniversary in a big way with an all-new perpetual calendar movement, the Audemars Piguet Calibre 7138. Making its debut in both the Code 11.59 and Royal Oak, the cal. 7138 is a landmark in traditional perpetual calendars. In fact, the movement is perhaps the most sophisticated and user-friendly perpetual calendar from an establishment brand. The calendar relies on the classic “grand lever” mechanism that’s been reinvented in an ultra-thin manner, but more importantly, the cal. 7138 employs an ingenious and innovative setting mechanism. Consequently, it is impressively intuitive and also foolproof. All the calendar indications are set via the crown, and the movement can’t be broken by setting it at the wrong time. Together, these features mark the cal. 7138 out as one of the most notable perpetual calendar movements on the market today. The cal. 7138 debuts in the Code 11.59 (left) and Royal Oak. Image – Audemars Piguet Initial thoughts The perpetual calendar has long been a key part of the history of Audemars Piguet (AP), especially after the bestselling ref. 5548 was launched in 1978. So a brand-new perpetual calendar for its 150th anniversary is fitting. At the same time, the calibre illustrates AP’s tremendous advances as a vertically integrated, industrial-haute horlogerie manufacture that has developed an splendid stable of in-house calibres in a relatively short period of time. The irony is that the cal. 7138 is almost...
