Outside of the color change on the case and bracelet, this is largely the same watch as Porsche Design’s current standard bearer for the Chronograph 1, the All-Black Numbered Edition. Like that watch, the new 1975 Limited Edition features a Porsche 911 dashboard-inspired matte-black dial with white markings, white hands and a red chronograph seconds hand.
The only differences on the dial are found around the day-date window at 3:00. The new watch uses Porsche Design’s vintage logo and script instead of the modern style of the All-Black version, and it also omits the words “chronometer certified,” though the watch’s movement remains COSC-certified.
Speaking of the movement, that’s another difference between the modern black and non-black Chronograph 1s, albeit a minor one. The 1975 Limited Edition uses PD’s manufacture calibre WERK 01.240, which is an updated version of the WERK 01.140 powering the All-Black. Both are COSC-certified automatic chronographs with flyback functionality, a bilingual day-date window (English and German) and a 48-hour power reserve.
The casebacks are also different. While the All-Black features a sapphire display back showing off the movement, the uncoated model has a solid caseback featuring the vintage Porche Design logo and commemorating its status as the 1975 Limited Edition, including its number from 1–350.
