Chrono24 Certified is available on this listing and I encourage any buyer to use it. I'd rather you verify the watch independently than take my word for it. Silver dial with the correct blued outer date track and red-tipped pointer date hand characteristic of the reference. Applied baton markers with original aged lume. Signed Heuer crown and signed case flank. Unpolished case retaining original proportions and sharp lug edges. Caseback shows light to moderate scratching from decades of wear — never polished or refinished. Case shows honest wear at the bezel and band edges. Acrylic crystal with light surface marks. Chronograph, day, month, and pointer date all function correctly. No known service history; I'd recommend a service as with any unserviced vintage chronograph, and the watch is priced accordingly. No box or papers. Aftermarket leather strap. Private seller, happy to answer any questions.
