Product Description

First introduced in 1969, the Speedtimer was a major innovation milestone in Seiko’s watchmaking heritage.

This latest design is the first Speedtimer to feature the robust and reliable 6R in house automatic calibre and the slimmest ever 6R model in the brand’s history, at just 11.95mm depth.

With its super-hard coating, the flowing case shape of this model was first used in 1972 on the famous Seiko ‘Panda.’ Under the curved sapphire glass, a silver-white dial is encircled by a countdown timer function. The strong Lumibrite coating on the inner-ring reference triangle allows for the countdown timer to be used with clarity during both day and night. Compact and comfortable, this Speedtimer has a diameter of 39.5mm, and a water resistance of 200m.

The in-house 6R55 automatic calibre is accurate to -15/+25 seconds per day, with a three day power reserve.

Prospex is a combination of the words ‘Professional’ and ‘Specifications.’ Seiko Prospex timepieces are designed to be practical, reliable and durable; to meet the high standards required in extreme environments for sports lovers and adventure seekers alike.

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.
