Introducing the beautiful vintage 1980s Seiko 5 watch with a vibrant green dial and burnt orange accent dial called the 'Watermelon'. An excellent piece combining retro charm with reliable functionality. This timepiece is from Seiko's esteemed "5" series and is a testament to the brand's commitment to quality entry-level watches. 


The Seiko 5 is housed in a 36mm stainless steel case and features golden hour markers and hands to ensure effortless legibility, even in low-light conditions. While the day-date display at the 3 o'clock position adds practicality to its classic design. The day date can be presented in English and Arabic options.


Functionality lies at the core of this great watch. Powered by automatic movement, the Seiko "5" guarantees accurate timekeeping without needing batteries. Embrace the allure of the 1980s with the vintage Seiko "5" watch, a nostalgic timepiece that seamlessly blends style and reliability.


Please note this watch comes with an aftermarket bracelet which suits the watch well but does have a firm clasp. We'd recommend testing for comfort and size, but if not suitable, pairing it with a colourful Nato strap.
