Hand wound movements work by manually winding the watch with forefinger and thumb, usually once a day by turning the crown in a clockwise direction until a point of resistance has been reached. Manually wound watches can generally be slimmer in case size due to a lack of rotor - which are used in automatic watches - and are also favoured by purists who enjoy the ‘hands on’ feel a manually wound watch can create by requiring the wearer to physically play a part in the accurate timekeeping of his/her watch. Brands like NOMOS Glashütte, Pequignet and Habring² take great pride in the quality of their in-house manufactured, manually wound movements.
