Timestamp : https://imgur.com/gallery/vbuKFoc SEIKO SPEEDTIMER BULLHEAD 1976 Vintage automatic chronograph watch Cal 6138 B JAPAN J 6138-0040. Measurements: 44 mm without crown and 48 mm with crown. Good condition although with obvious signs of the passage of time and use. For wrists up to 21 cm.. It's keeping good time fully serviced recently. The chrono functions all work beautifully and everything resets to zero. It has scratches all over the case and bracelet but has never been polished which is so rare with these pieces. All of the original brushing and case lines are there. The dial is just about perfect! Just amazing. It's so rare to see the dials in this kind of shape. This is an excellent all original example of a Seiko Bullhead JDM variant. It is the Speed-Timer version and best of all it comes with its original expansion clasp bracelet.. 🔹Brand Seiko 🔹Model SpeedTimer 6138-0040 🔹Gender Men's 🔹Movement Automatic 🔹Caliber 6138B 🔹Case material Stainless Steel 🔹Diameter without crown 44 mm 🔹Diameter with crown 48 mm 🔹Inside Lug Width 20 mm 🔹Lug to Lug 42.5 mm 🔹Bracelet material Stainless Steel 🔹Bracelet measures For wrists up to 21 cm 🔹Decade 70s 🔹Year 1976 🔹Condition Fine 🔹Box No 🔹Papers No 💠 Payment Method PayPal / Wise 💠 Shipping will be through UPS
