The rainy days of April have ebbed away and the summer season has finally arrived. The sun now reveals its broad toothy smile and warmly looks down on the citizens below. Like many individuals, I now contemplate travelling to foreign climes for two weeks holiday, basking in the UV-rich light and occasionally dipping my toes into a crystal clear sea.

An annual dose of sea and sunshine can wonderfully calm a troubled soul, bestowing a sense of wellbeing. I am reminded of these healthy dividends with the new Chronoswiss Sirius Flying Regulator Jumping Hour. This steel cased watch features a galvanic blue guilloché dial paired with vivid galvanic orange dial elements, evoking thoughts of the summer. Indeed, its cheery dial vista warms the soul and proves a fitting metaphor for summer.

The dial

Chronoswiss has a long history of producing regulators, harking back to 1987. The founder of the Swiss watch company, Gerd R. Lang, took the strategic decision to produce regulators, providing a point of differentiation from many of the watches available at the time.

Historically, regulators were used as reference clocks or watches by which other timepieces were set. The centrally positioned minute hand would take prominence, dominating the dial area with hours and seconds being shown on two separate subdials.

Since the inception of Chronoswiss, the regulator has been a staple in the company’s collection. The watch company from Lucerne has produced many iterations of the regulator, often sporting elegant guilloché dials.

The Chronoswiss Sirius Regulateur Jumping Hour CH-8323 eschews a circular subdial, displaying the prevailing hour using a digital display. Despite the striking design language of this model, it still evinces a traditional character, courtesy of the various motifs on the dial, including flinqué, satiné circulaire and basket pattern.

At Baselworld 2016, Chronoswiss revealed a new model, the Sirius Flying Regulator Jumping Hour – Ref. CH-8323-BLOR, which shares some of the DNA of the aforementioned Sirius Regulator Jumping Hour CH-8323. However, owing to the dial design and vibrant shades employed, this new model exhibits a greater sense of modernity.

The blue dial canvas is festooned with a plethora of exquisite details. The guilloché motif is stamped, allowing Chronoswiss to deliver this timepiece at a very accessible price point. The motif is to a design conceived by the watch company and delightfully engages with ambient light, bestowing areas of brilliance and shade which change when holding the watch at different angles.

The term ‘Flying’, used within the nomenclature of this watch, refers to the floating character of the minute and seconds tracks. These tracks are galvanic orange, snailed and marked with blue Arabic numerals and blue intervening strokes. Positioned at 1 and 11 o’clock are angled plinth-like mounts which hold the minute track above the dial surface. Likewise, at 5 and 7 o’clock similarly styled mounts support the seconds track. Each mount is held with two thermally blued screws, reinforcing the perception of quality. By adopting this design language, the dial vista is imbued with fascinating depths which accord a rich character to the display. The curving line of the sapphire crystal augments the three dimensional quality of the dial composition still further.

The case

Measuring 40mm in diameter, with a thickness of 12mm, the stainless steel case should prove universally suitable, fitting a myriad of different sized wearers. I found the case accorded a comfortable fit with my wrist. Moreover, the prominent onion-shaped crown did not chafe or gouge into my arm, despite its notable scale.

The size of the crown confers an alluring appearance and proves highly practical when adjusting the time or winding the watch.

The bezel and upper surface of the lugs are highly polished. The case band, case back and sides of the lugs are satin brushed, whilst the underside of the lugs are, once again, highly polished. The mix of surface treatments works well. Indeed, the satin brushed surfaces, with their muted character, accord a tasteful contradistinction to the ebullient temperament of the highly polished areas.

I especially appreciate the slender band of fluting which delineates the bezel from the caseband. It is a magnificently graceful detail which heightens the perception of luxury. A further band of fluting appears at the junction between the case band and the case back, imparting a sense of balance.

An exhibition case back delivers views of the self-winding movement within.

The movement

The Chronoswiss Caliber C.283 is automatic with a power-reserve of 42 hours. The balance has a frequency of 28,800 vph (4Hz) and the movement contains 27 jewels.

The oscillating mass is open-worked and runs on steel ball-bearings, ensuring a smooth rotating action. The open-worked sections of the oscillating mass accord views of the bridges beneath. The rotor is adorned with Côtes de Genève motif and the bridges feature perlage. The lever, escape wheel and screws are also polished.

Closing remarks

The colour scheme of the Chronoswiss Sirius Flying Regulator Jumping Hour brims with vitality, effervescing with life. The blue and orange hues employed are a wonderful metaphor for the summer and caused a broad smile to appear on my face when we were recently introduced at Baselworld.

However, the attributes of this watch are not restricted merely to said colourway. The fascinating design of the guilloché motif and the eye-catching, artful play with depths, helps to distinguish this timepiece as special.

I liked the Chronoswiss Sirius Regulateur Jumping Hour CH-8323 I reviewed last year but, bearing in mind the modest price premium, I would now favour the new ‘Flying’ version of this timepiece.
