Studio Underd0g Did THIS for £750? | New 04SERIES

The new Studio Underd0g 04SERIES Calendar brings a moonphase, retrograde pointer date and weekend indicator together in a £750 automatic watch.

We also need to talk about thickness: the case measures 10.5mm excluding the crystals, but the total thickness is 13.5mm. Available in 37mm and 38.5mm case sizes, the 04SERIES introduces four colourways: Cloud10, Arabian Sky, Shepherd’s Delight and 0vercast. Other specifications include sapphire crystals front and back, 50 metres of water resistance, a 4Hz automatic movement with hacking, and leather straps by The Strap Tailor.
