TAG Heuer 300m Automatic Diver; its operation, reset function, and all features are flawless. It has a 43 mm case diameter. Manufactured in 2018, it is an automatic chronograph. Four links were added because the original bracelet length was too short (shown in the photos). It fits wrists up to 19.5 cm with the internal extension closed; if you remove those extra links and use the internal extension in the open position, it fits wrists up to 23 cm. Its overall condition is excellent. It will be carefully packaged and shipped with the included TAG Heuer box. This is a watch that will truly delight you. May the best offer win! Best regards.
