Manufactured during the 50s and 60s, the Valjoux 92 calibre gave way to the quartz at the end of the sixties. Although it was a very popular chronograph movement at the time, it is a very rare calibre today. To make this exceptional piece even more unique, Speake-Marin decided to dedicate this model to Only Watch by way of its colours. The 42 mm Piccadilly titanium case houses a three-dimensional blue dial, with two floating counters: the white counter for the small seconds, while the grey measures the minutes of the chronograph. In the centre of the dial, the “London Chronograph” engraved rotor takes the form of the Speake-Marin logo and rotates with the hours. The orange hands provide a touch of intensity to the soft blue and the elegance of the grey.
