SevenFriday M-Series watches

The SevenFriday M-Series (M1, M2) was the Zurich brand's second line, shown in June 2014 after the P-Series. SevenFriday was founded in 2012 by Daniel Niederer and makes large watches with an industrial look; the M-Series keeps the P-Series' square 47 mm by 47 mm lugless case, moves the crown to the left, and takes its design cues from industrial machinery such as turbines.

What sets it apart is the display. There are no conventional hands: three concentric discs show the time, with the hours on the outer disc, then minutes, then seconds towards the centre, and a red vertical line marks the seconds. The time is read from the outside in. Inside is a modified Miyota 8215, a Japanese automatic calibre from Citizen's Miyota arm, which is why the watches are not Swiss Made despite the Zurich address. The crystal is mineral glass with an anti-reflective coating.

The M1 and M2 differ in finish rather than mechanics. The M1 is the steel version; the original M2 dresses the same case in black-coated steel, with cream discs over a black dial. Other references change the dial colour: the M1/01 has a silver dial, the M1/03 and M2/02 grey ones.

Around the core models sit limited runs on the same 47 mm, 13 mm thick case: the black-dial M1/02 UAE Edition in 71 pieces, the M2/01 Gulf Run X (M2/02GR) in 50, the grey-dial M2/02 Al Boom (M2/02AB) in 100, and the black-dial M1/04 Punk in 450.
