Overview
U-Boat Capsoil Darkmoon Soleil Blue SS Quartz Watch, 44 mm.
A blue sunray dial gives this oil-filled watch its depth and retro character. Beneath the domed sapphire crystal, the fluid creates a three-dimensional effect around the hands, while a visible compensation bubble is part of the distinctive display. The 44 mm case is crafted from 316L stainless steel.
Inside, a Swiss Ronda 712.3 quartz movement runs immersed in lubricating oil. A screw-down crown with a double security system controls the time setting, and the screw-down case back provides access for quick battery changes and oil replenishment. Water resistance is rated at 5 atm.
Super-LumiNova on the hands and indices adds a luminous contrast to the blue dial. A black silicone strap, 22 mm wide and secured by a stainless steel buckle, completes the Italian-made watch.

Better than expected! Great service and tracking can’t be happier!

This is my 4th U-Boat watch and in my opinion the best looking one so far.
J
The picture doesn't do it service. I have or had a Rolex, Panerai, Maurice Le Croix, Brietling and a Glashutte and this is the best valued watch I've had.
I'm afraid to say it but they aren't charging enough

Your order arrives brand new in its original U-Boat packaging, with all official documentation and the U-Boat warranty card, stamped and dated by us.
