This collection has been created with a 36mm case; an ideal size for Field watch fans and traditional Seiko 5 enthusiasts. With the combination of Arabic numbers and different spot and baton markers, ‘Midfield’ expresses a sports aesthetic enhanced by its durable stainless-steel case and “Green zone” khaki coloured nylon bracelet.
The Seiko 5 Sports ‘Field’ collection was created with an ‘in the field’ military design – taking inspiration from a style originally called a ‘trench watch,’ created to be robust and reliable in tough conditions – echoing the Seiko 5 Sports characteristics.
Seiko 5 Sports is known for over fifty years of reliability, durability, performance and value. ‘’5’’ represents the original five key features of every Seiko 5 still present today: Automatic movement, Day-date display, Water Resistance, Recessed crown and Durable case and bracelet.

In addition to our 30 day returns policy, all items purchased from 1st October 2026 can now be returned until 15th January 2027, terms apply.
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.

Lovely every day field watch. Having bought a Certina dress watch from firstclasswsatches before they were my first choice when looking for a more casual watch. I've popped a different strap on it as I'm not a fan of the way classic natos sit on my wrist, it looks great! Service top notch again, won't use anyone else!! Also it was a bargain!
