Product Description

"This watch shape is nicknamed by Seiko fans as a ‘turtle’ -  its silhouette, side view and watch case back resemble a turtle with its curved comfortable shell. To divers, sea turtles are symbols of good fortune. This is the diver’s watch that, just like the sea turtle, is loved by many diving enthusiasts. Seiko Prospex watches are designed for sports lovers and adventure seekers whether in the water, in the sky or on land. The PADI timepiece collection is exclusive to Seiko, as the only global watch brand to design a range of professional diver’s watches in official colours featuring the PADI logo. PADI (The Professional Association of Diving Instructors) is the world’s leading scuba diving training organisation, unifying divers around the globe who share a passion for adventure and love for the ocean. Since launching Japan’s first diver’s watch in 1965, Seiko’s innovative watchmaking has changed global dive watch standards."

Items will be sent by your chosen delivery method once they are back in stock. For UK orders paid by card, Apple Pay or Google Pay we do not charge you until we are about to despatch your order; PayPal, Amazon Pay, Klarna, finance and international orders are charged when the order is placed.

Returns Policy

We aim for you to be absolutely delighted with your purchase and therefore offer you 30 days to change your mind on your purchase. You may do this by using the form provided with your order or otherwise. We will provide a refund of all payment received (not including delivery upgrades), usually within 2 working days of receiving your return (it may take a little longer during busy periods or for more complex returns). This will be made to the original payment method. For most payment methods it will take 3-5 working days for this to show on your statement.

Please ensure items from your order are suitable before wearing as we are unable to accept items which have been worn under our returns policy.

Returns are free on all UK orders. For orders under £500, you may generate a free tracked and insured returns label on the Royal Mail website (opens in a new window). You can print this label and send it back at any local Post Office at no cost to yourself. It is also possible to have the label printed at Post Office using the QR code from the confirmation email. Please retain the proof of postage receipt. Unfortunately we are unable to refund return postage for orders under £500 sent back by other methods, so we recommend printing the free postage label provided. For orders from £500 to £2,500, the Royal Mail label does not cover the value of the item, so please send it back by Royal Mail Special Delivery, insured for its full value, and we will reimburse the postage separately (please keep your proof of postage — full details are on your receipt), or contact us and we can arrange a collection. For orders over £2,500, please contact us and we will arrange the return for you. For international returns, you will need to bear the cost of returns postage. Please ensure the watch is returned to us in an unworn, new condition with all the original packaging (manufacturer's manual and guarantee if applicable). Please ensure items from your order are suitable before wearing as we are unable to accept items which have been worn under our returns policy. We reserve the right to make deductions for unnecessary damage caused to the product by yourself.

For UK orders we are also able to offer an exchange to a different product if required, please specify this when returning your product. For international orders, please return the item for a refund and place a new order for the product you would like.

If a fault develops with a watch that is outside of the 30 day returns period or is no longer in a new condition the watch can be returned to the manufacturer under the terms of the guarantee (we are an official UK dealer for all brands on our website) so that they can rectify any issues. For more information please see our returns policy page.
