The watchmakers at Porsche Design have always had a flair for simple designs that leave out all excess. Now, they’ve added three more watches to their Flat Six P’6300 collection, a series that embodies the company’s tradition of simplicity.

The dial of the P’6350 is available in ten different colors (actually, so do some other parts of the watch, so you get to choose from several combinations). It has a very clean look, with minimal embellishments. Six Arabic numerals mark the hours. At three o’clock, instead of a numeral, there is an aperture for the date. The spaces for one, five, seven, nine, and eleven are simply left blank, with just a wide marker on the chapter ring to indicate the hour. Outside of the thick hour markers, smaller numerals signify the minutes. The case is 44 millimeters and houses a Swiss-made, automatic winding mechanical movement.

The P’6351 is basically a smaller version of the P’6350, meant for ladies, 40 millimeters instead of 44. It has the same movement, the same simplistic design as the larger model, and it also comes in a variety of color combinations. It’s just a little bit on the robust side for a ladies watch, but it still looks great.

Easily the most exciting of these three timepieces is the P’6360 Flat Six Automatic Chronograph. This one obviously has more embellishments and extra touches than the others, and that’s not just because of the chronograph. The design of this watch was inspired by automobile racing (as many watch designs are). Its dial is made of patterned carbon fiber, and there are three sub-dials for the chronograph. The half-hour counter is located at 12 o’clock, the 12-hour counter at six o’clock, and the small seconds counter is at nine o’clock. The dial only has four hours that are marked with Arabic numbers, two, four, eight, and ten. Even with the sub-dials and textured dial, however, the design remains overall the same as on the P’6350.

There is a tachymeter scale around the inner ring of the bezel. A double aperture at three o’clock displays the day and date. They really used a lot of lume in the dial, so it’s always easy to read. The stainless steel case is 44 millimeters, like the P’6350. There are versions with PVD coating as well. The movement is an automatic, the ETA Valjoux 7750.
