It has been a while since Certina launched a new product. Recently, we saw several updated and redesigned models. One of them is DS Podium GMT Chronograph Aluminum Watch that houses aluminum case as its name suggests.
Aluminum is almost twice as light as titanium. The watch is housed in a round case which measures 42mm in diameter. Together with the strap, the total watch’s weight is only 55 grams.

Besides the fact that it is extremely lightweight, this material opens up new colorful options to the Certina DS Podium GMT Chrono series. It brings colorful new options. The version with the referent number C001.639.97.057.03 is dressed in bright Certina green which is light enough to accompany the most active of lifestyles. There is also a striking red version and a sand-colored one (their referent numbers are C001.639.97.057.01 and C001.639.97.037.01).
Each of these three newcomers boasts the same highly-durable, scratch-resistant anodization surface treatment.

The beating heart of the new Certina DS Podium GMT Chronograph Aluminum is supremely precise ETA Precidrive movement with GMT function for a second time zone. The impeccable mechanism also offers standard timing functions such as 60 minutes and 60 seconds, as well as full 12-hour timing with Start-Stop and Add/Split functions. The watch is equipped with a practical EOL (end-of-life) warning system.
Underneath the front sapphire glass there is a clearly organized matte-black dial for green and red versions, and the silver one for the sand-colored model. The dial incorporates bold luminescent Arabic numerals 3, 9 and 12, as well as indices and hands which guarantee perfect legibility of the time, regardless of the light. There is also a date display which is located at the 6 o’clock position.

On the right side of the case there are two chronograph pushers, as well as a protected crown with monogrammed green “DS” on its tip which stands for Certina Double Security or Double Safety protection system that provides high resistance against shocks and water pressure. The water resistance is assured up to pressure of 100 meters (about 330 feet).
The green and red versions are attached to moulded black rubber straps with pin clasps, whilst the sand-colored model is secured to the wrist with a white strap.
Each of three DS Podium GMT Chronograph Aluminum timepieces can be purchased for CHF660 which is approximately $685.
