Clerc Hydroscaph Limited Edition Central Chronograph (ref. CHY-554) in Black DLC Swiss

Like the sporty Sinn EZM 10 “Einsatzzeitmesser” Pilot Chronograph that was revealed last year, the new Clerc Hydroscaph Limited Edition Central Chronograph (ref. CHY-554) comes equipped with a central chronograph minutes hand that not only makes the timekeeper’s dial more interesting to look at. The design also significantly simplifies the task of measuring short periods of time: something that most common chronographs with their tiny, difficult to read totalizers are not always good at.

Although, thanks to a pair of thin chronograph hands of white and orange colors, the new timekeeper looks like a split-seconds chronograph, it is in fact a “normal” chrono with one of the hands counting seconds and the other tallying minutes.

With such a design the Swiss watchmaker Clerc kills two birds with just one expensive stone: it gets rid of one of sub-dials allowing for the rest of elements more room to breathe and makes it easier to read the 60-minute totalizer for persons with poor eyesight.

To somehow counterbalance the small seconds indicator placed at 3 o’clock, they also placed a 24-hour day/night indicator at 9 hours. There is also a date window at 6 o’clock.

It is reported that the functions are powered by an “exclusive” caliber CO608 automatic movement. I am not sure about its origin, but, as far as I know, the watchmaking brand has its own manufacturing facilities, so there is a good chance that this is their own movement, not some ETA 7750 derivative with a third-party add-on module.

As usual, the movement rests inside an oversized, rugged-looking body.

Measuring almost 44 millimeters in diameter (and almost 50 millimeters in width if you include the lateral protections,) the stainless steel case of the watch is treated with black DLC coating, which makes this model almost scratch-proof.

Its contrast, highly legible dial is, too, protected from the elements and salty water (this is a diving watch, after all) with a glare-proofed, 4-mm thick synthetic sapphire crystal.

Well, I can’t say that I am terribly excited about this piece, it is way too rugged and massive to my taste, but, giving Clere Geneve their due, I must admit that the watch looks very original and may be a good investment for those searching for a brand that goes unbeaten path.

The new Clerc Hydroscaph Limited Edition Central Chronograph watch was presented earlier this month at Baselworld 2012 show and will be produced as a 500-pieces limited edition issue. Price is still to be announced, but don’t expect this watch to cheap.
