Omega’s latest is an unusual combination of a 600 m-rated dive watch with a Cottier-style world time. The Seamaster Planet Ocean Worldtimer shares the oversized ceramic case of the Planet Ocean Deep Black, but is the first model in the collection to incorporate a world time complication.

Initial thoughts

While the Worldtimer makes a bold statement, a US$14,800 price tag and substantial case dimensions may limit its appeal – particularly for those with average-sized wrists. Still, it offers a somewhat paradoxical and oddly specific combination of features, so someone seeking a world time watch ready for saturation diving, there are few other options. Of the two available colourways, I would choose the low-key grey edition for its greater versatility compared to the turquoise version.

Worldtimer

Offered with either turquoise or grey accents, the new Planet Ocean is housed in a black ceramic case measuring 45.5 mm in diameter and 17.4 mm in thickness. Signature Seamaster case elements, including twisted lyre lugs, a helium escape valve, and “Broad Arrow” hands, complete the design.

The standout feature the world time complication with a cities disc and 24-hour ring. At the centre is a titanium disc displaying a view of the Earth from the North Pole, with continents and colours rendered with varnish and laser engraving. A 24-hour ring in transparent hesalite is shaded in black and white to denote night and day. The chapter ring for the hours is embellished with a honeycomb pattern, while the outermost ring has 24 cities representing the 24 primer time zones.

Powering the watch is Omega’s in-house self-winding cal. 8938, which is a Master Chronometer certified by METAS and therefore magnetic-resistant up to 15,000 gauss.

Operating at a frequency of 3.5 Hz, it provides a power reserve of 60 hours. The movement is decorated with radial striping arabesque, along with contrasting blackened screws, barrels, and balance wheel.

In celebration of birthday, Zenith presents a trio of chronographs entirely in blue ceramic, the 160th Anniversary Editions of the Chronometer Sport, Defy Skyline Chronograph, and Pilot Big Date Flyback. Each retains the specifications of its steel equivalent, with the only distinction being the case and bracelet material.

Initial thoughts

Best known for the El Primero high-beat automatic chronograph, Zenith arguably does best at chronographs, and that’s exactly what it’s doing for its anniversary. The reimagining of Zenith’s best-known models in blue ceramic is on trend – maybe a bit too trendy – with brands like Audemars Piguet having already done it. That said, the anniversary trilogy does offer a striking new alternative to anyone seeking an El Primero with a whole new aesthetic.

The use of ceramic for both the case and bracelet, however, means each of the trilogy models is notably pricier than the equivalent model in steel. That’s acceptable for an anniversary limited edition, but not quite the same value proposition as the steel variants.

Blue ceramic

The Chronomaster Sport, Defy Skyline Chronograph, and Pilot Big Date Flyback each retain the same dimensions and movement as their respective steel models, except that the case and bracelet are now in blue ceramic modelled on Zenith’s signature hue.

According to Zenith, blue ceramic was an undertaking that involved months of research and development. Blue ceramic is significantly more challenging to finish than white or black ceramic, owing to its integrally coloured composition. As a result, exacting craftsmanship was required to shape and finish each ceramic component, with the surface finishing ranging from brushed to polished to blasted depending on the model.

All three watches are equipped with the latest-generation El Primero movement of the 36XX family. Like its namesake from 1969, the new El Primero runs at a high frequency of 36,000 beats per hour, or 5 Hz.

While the Chronomaster and Defy contain the cal. 3600 with a 1/10th of a second chronograph thanks to a lightning seconds hand, the Pilot has the simpler cal. 3652, which along with its strap, explains its more affordable price tag.
