IWC further implemented a micro-adjustment system (as you see in the picture), the one we know already from the A. Lange & Söhne Odysseus or the Glashütte Original SeaQ bracelets. The system is integrated into the clasp and activated by the logo pusher, upon which the length can be adjusted by about one link size. All this in an easy, confidence-inspiring way – perfect for one-the-fly – corrections. Also, the system really does not add much to the thickness. theeclecticum.com'' Brand: IWC Model: Pilot Chronograph Ref: IW377704 Movement: Automatic Case: Steel Diameter: 43mm without crown Strap/Bracelet: Original Strap/Bracelet length: Can fit up to 18cm wrists Clasp: Original Condition: Worn and in very good condition Extras: Certificate of Originality, invoice Shipping via Fedex or UPS (Its so safe and fast) #Watchbonafide
