Description
This piece is a re-interpretation of Japan’s (and Seiko’s) first ever Diver’s watch which was released in 1965 and marked the beginning of Seiko’s expertise in diving watches. From 1966-1969, this watch was worn by members of the Japanese Antarctic Research Expedition, proving its durability and reliability in challenging environments. With a 39.5mm case design inspired by the original 1965 piece, it carrys the name ‘Marinemaster’ from Seiko’s heritage in diving watchmaking, the aesthetic is modernised with an elegant marine sports style.

Under a box sapphire crystal glass is a refreshing Aquatic green dial with a textured horizontal pattern. Aside from mirror-finished lugs, it features rectangular Lumibrite-coated indices, reminiscent of the original 1965 Diver. In a more compact case size than previous re-interpretations, it recreates the silhouette of the first piece. The super hard coated case is only 12.3mm, making it the slimmest Seiko mechanical diver at ISO Diving Standard, despite its box sapphire crystal glass and sapphire exhibition case back.

Whilst being slim, the newly developed in-house 6L37 mechanical calibre maintains high precision of +15 to -10 seconds per day, and a power reserve of 45 hours. 200m water resistant.

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.

30 Day Returns & Exchanges

Although we do our best to ensure our pictures and descriptions explain our products as clearly as possible, sometimes you may find that when your item arrives it's not quite as you expected, it doesn't fit properly or you may have simply changed your mind.

Don't worry - we have a 30 day change of mind guarantee on all our items.* All you need to do is send the item back in the post (you have to cover these costs) or pop into your local Chapelle store so they can return the goods on your behalf or arrange for a different size. Products must be returned unused, in a saleable condition and with all original packaging. You are responsible for ensuring the product is not damaged whilst in your care.

*This excludes personalised, bespoke or specially ordered items. This also excludes any ring sizes outside our standard range; I-U for ladies and P-Z+1 for men.

Collection & Delivery
Collection

Your chosen store will contact you once your order is ready for collection. In some circumstances we may supply rings in the nearest size available (especially if more than one ring is ordered) which can be adjusted to fit once the item has been paid for and the branch have confirmed the finger size. Items that need to be specially ordered are not available for this service and must be paid for in full before ordering. The store will hold your order for 1 week and then it will be returned to stock.


Delivery

Please note the expected dispatch dates stated for each product as this indicates how long it will take us to dispatch your order. Express Delivery is offered for most items but this does not mean the item(s) will be dispatched any sooner than the expected dispatch date. Orders for multiple items will be dispatched together and are therefore collectively subject to the longest dispatch time stated. Parcels may be sent via courier which is a next working day service and requires a signature on delivery.


International Delivery

We offer international delivery within the EU and EAA on jewellery and most watches; sorry we are unable to dispatch heavy or bulky items and some selected ranges outside of the UK. Please be aware that local taxes and fees may be applied and the customer is responsible for paying these. International Delivery is a minimum of 3-5 working days from the expected dispatch date and may be considerably longer for more remote or distant locations.
