Up Close with the Patek Philippe Grand Complication Ref. 5951P-013

The most complicated, integrated chronograph made by Patek Philippe, the ref. 5951P is compact but offers much to admire. We go up close with it, complete with detailed photographs of the movement.

First unveiled in 2010 with a funky, and arguably ill-suited, red and black dial, the ref. 5951P subsequently evolved into a more pleasing version with Breguet numerals. Featuring the Geneva watchmaker’s top of the line chronograph movement topped with a perpetual calendar module, the ref. 5951P is a example of what Patek Philippe does best – traditional, high-end watchmaking.

Measuring just 37 mm in diameter, the ref. 5951P is a small watch by modern standards; its size is limited by the small movement. But because of the case material as well as its thickness, the ref. 5951P feels dense and hefty, not usually a quality associated with Patek Philippe watches. With a cushion-shaped case and Breguet numerals, the overall look look is derived from vintage chronographs of the 1930s (Patek Philippe has a remarkable rich archive of chronographs), but the style of the dial is modern. The position of the day and month windows, along with the leap year and day and night apertures, are thoroughly modern elements.

The black is a disc of solid gold, lacquered a glossy black and then topped with applied Breguet numerals in white gold. It’s finely made, and relatively legible for such a complex dial. But as with many chronographs, the main attraction is the reverse. The calibre CHR 27-525 PS Q is just wonderful to look at. Without the perpetual calendar mechanism (as found in the refs. 7059, 5959 and 5950), the CHR 27 is the thinnest split-seconds chronograph movement made today.

With the perpetual calendar on top it still remains slim, at just 7.3 mm high. But that is relatively high, compared to the 37 mm case diameter, giving it the solidity alluded to earlier. The details of the movement are outstanding, with a masterful level of decoration found on all its components. Especially beautiful are the remarkably slim steel springs of the split-seconds mechanism, as well as the elegantly formed, “S” shaped clutch lever.

For more close-ups of the movement, check out our in-depth look at the ref. 7059R split-seconds chronograph, which is equipped with the same base movement.


The ref. 5951P is priced at SFr500,000.

Hands-On with the Omega Globemaster Master Co-Axial (With Original Photos & Price)

Styled after the vintage Omega Constellation, the Globemaster may be vintage-inspired but it's powered by a cutting edge movement. Here's a hands-on look at the Globemaster, complete with review, photos and prices.

Introduced at Baselworld in March 2015, the Omega Globemaster is only just reaching stores. Though lacking the pop culture credentials of the Speedmaster Snoopy or Seamaster 300 Spectre, the Globemaster Master Chronometer is arguably Omega’s most significant wristwatch of 2015, being the culmination of a decade long effort to develop a more robust and reliable movement.

The mid-20th century influence

The looks of the Globemaster are familiar to those who understand vintage Omega watches, but it’s not quite a vintage remake. Instead it’s a blend of elements of from various Omega Constellation models from the 1950s to 1960s. The name itself was once applied to early Constellation watches in the 1950s.

Similarly, the pie pan dial, named after its shallowly domed, facetted shape, is taken from early Constellations, as is the inlaid star at six o’clock. Both the fluted bezel and tonneau-shaped case, on the other hand, can be found on the 1960s Constellation C. And on the back the relief medallion featuring an observatory has been the trademark of the Constellation line since its inception. It’s a reference to the observatory timing contests Omega took part in, back when such things still existed; they were terminated once Japanese watches started winning and the quartz crisis erupted.

A high-tech movement rigorously tested

Inside the steel Globemaster watches is the Master Co-Axial calibre 8900, while the gold versions are equipped with the calibre 8901 (identical save for the red gold rotor and balance bridge). These movements are the first with the METAS certification announced last year, making them Master Chronometers.

Developed by the Swiss Federal Institute of Metrology (METAS) and Omega, the METAS test is meant to be a neutral and stringent process that tests the entire watch (instead of just the movement as COSC does) and demands higher standards than COSC, the best known chronometer testing body.

METAS requires an average daily rate of 0 to +5 seconds, while COSC needs just -4 to +6 seconds to pass. And METAS also tests for magnetism resistance, something the Master Co-Axial excels in, being resistant to magnetic fields of beyond 15,000 Gauss, equivalent to that generated by a small magnetic resonance imaging (MRI) machine. Omega accomplished that with proprietary non-magnetic alloys for key components of the escapement, as well as silicon for other parts. The Master Co-Axial movements are the most magnetism resistance in the industry, by an enormous margin. That being said, Omega also sends the movements to COSC for certification, so each Globemaster is somewhat redundantly also a COSC chronometer.

Like Omega’s other top of the line movements, the calibres 8900 and 8901 are finished with a spiral Geneva striping Omega calls Cotes Arabesques, with all the screws treated with a black finish. Though all the decoration is obviously mechanically applied, it is attractive and as good as the best in this price range. All of this can be admired through the display back, unlike conventional magnetism-resistant watches that require a soft iron cage inside.

Materials and variants

Fittingly with its vintage style, the Globemaster is 39 mm in diameter, just right for the correct retro feel. It’s offered in a diverse range of materials, starting with the base model in stainless steel. Despite being entry-level, the steel model is not entirely steel; its bezel is made from tungsten carbide, a hard, grey metal usually used for the tips of industrial drills.

Two-tone steel and gold models are also available, as are solid gold models. Both are available in either yellow gold or Omega’s patented Sedna gold, a red gold alloy that does not fade over time.

In steel and yellow gold

The top of the line model is the comically expensive platinum limited edition of 352 pieces. This has a solid platinum dial with a grained finish, with the white gold hour markers and hands filled with dark blue enamel. Similarly, the observatory medallion on the back is also in blue enamel. And it’s fitted on a leather strap stitched with platinum threads.
