The IWC Aquatimer Chronograph 3767 was introduced in 2009, marking the return of the external rotating bezel to the Aquatimer – a feature not seen since the 2004 discontinuation of the reference 3536.The case of the Aquatimer Chronograph measures 44mm across, at a height of 15mm. The case of this reference was only available in stainless steel; rubber-coated for the Darwin Foundation model. It was discontinued with the introduction of the next generation of Aquatimers in 2014.Reference
