All about the OLLECH & WAJS OW Astrochron
The OLLECH & WAJS OW Astrochron is a chronograph of extraordinary quality, worthy of continuing the Astrochron's legacy today, and we have striven to ensure that this new interpretation rises to the challenge. With a water-resistance of 50 ATM (500 m), the new model far exceeds the original's deep-diving capability and exceeds the Swiss chronometer standard.
OLLECH & WAJS OW Astrochron in detail
Further updates include a 360-degree rotating compass bezel and a 20-minute dive scale. These additional functions, combined with a five-minute regatta counter, extra-thick sapphire crystal, and a unique four-gasket pusher system, make the new OW Astrochron equally competent above and below the water.
Inside the brushed 316L stainless steel case is a successor to the historic Valjoux 72 movement that powered the first Astrochrons. In our workshop in the Swiss Jura, a custom-engraved automatic Valjoux 7753 - with an OW-made rotor - is regulated, adjusted, and power reserve tested in five positions, thereby earning its OW precision rating.
As a final homage to its predecessor, the new chronograph revives the striking North Atlantic blue dial of 1968.
The OW Astrochron S is presented on the OW S-Type Mark II bracelet, inspired by those found on many Ollech & Wajs models of the 1960s. The links are individually crafted from a solid block of 316L stainless steel, before being carefully brushed, assembled, and screwed by hand. This process prevents the usual stretching common to pressed-steel bracelets, ensuring both longevity and comfort for the wearer. The bracelet's double safety folding clasp prevents accidental opening.
The OW Astrochron also comes with a hand-made Perlon regatta strap, ideal for summer activities. Woven exclusively for OW - from premium-grade, lightweight and highly water, salt, and oil-resistant braided nylon - the regatta strap offers a pleasant blend of comfort and durability. The distinctive two-tone pattern echoes the Astrochron's dial colours, and those familiar with the international maritime signal flag system may also recognise the nautical code for J - Juliet. The strap is finished with a brushed stainless steel buckle, signed with "OWZ 1956". Combined with the Astrochron's extreme 500m deep-diving capability, this seafaring complement is ready for any challenge – in, on, or around the ocean.
Whether you are exploring a wreck, investigating a theory, or simply gazing at the stars and discovering new possibilities, the new OW Astrochron could be the perfect all-round chronograph.

FAQs
About David from WATCHDAVID
My name is David, and I've been deeply involved with watches for many years – not just as a dealer, but primarily as a tester, photographer, and classifier.
Since 2018, I’ve been running WATCHDAVID as an independent watch project featuring reviews, videos, and real-world wearing experiences. Many of the watches you'll find here have been on my own wrist – often for extended periods.
WATCHDAVID.SHOP is intentionally personal. I only sell watches that I genuinely stand behind – no anonymous mass-produced goods, no dropshipping, no "quick trends." Experience, transparency, and honest assessment are paramount to me.
And yes: I am not an anonymous seller. I enjoy good food, sneakers, and photography – and I have a proven weakness for Kinder Chocolate.
If you have any questions or are unsure, feel free to contact me directly. I will respond personally.
Shipping & Insurance
Within Germany and the EU, shipping is free of charge. Shipping is handled by DHL and insured up to €500, €2,500 or €25,000, depending on the watch's value. The watches are therefore always sufficiently insured.
You can find the delivery time in the description and/or below the shopping cart button. Some watches are only produced after an order is placed, while others are brand new and, for example, will only be available in a few weeks (so-called PRE-SALE), etc...
Revocation & Return Shipping
You can revoke your purchase within 14 days of receiving the goods.
I will cover the return shipping costs for you.
IMPORTANT: Do not send the watch back yourself; I will send you the free return label.
To do this, please simply contact me. david@watchdavid.com
It is also important that the watch is unworn and free of any signs of wear. After a successful inspection, I will refund the purchase price to you. The refund will be made using the same payment method you used for the purchase.
Authenticity & Condition of the Watches
I guarantee that all watches I offer are exclusively new, original goods. The watches come directly from the manufacturer and have had no previous owners, unless I explicitly state otherwise (e.g., so-called PHOTO WATCHES).
As an official dealer, I exclusively offer authentic products. These are offered in their original packaging, with a warranty card, etc., just as they are delivered by the dealer. Everything in a so-called Full Set. Some deliver more, some less...
Warranty & Service
All watches purchased from me come with the international manufacturer's warranty, which is usually two years. Some brands even offer a warranty of up to 5 years.
Should a warranty claim arise, I will take care of shipping the watch to the manufacturer or the responsible service center for you and will also organize its return to you. In addition, I will handle all communication with the manufacturer, so you don't have to worry about anything.
Even after the warranty period has expired, I will remain your contact person and support you with service questions or repairs.
No answer received?
You contacted me, via the contact form, about the price proposal, directly by email, chat, but you didn't receive a reply?
Then please check your SPAM folder! Many providers are getting crazier and crazier and are sending more and more to spam.
I usually answer every inquiry within 24 hours at the latest. On weekends, it may take a little longer. As a rule, I reply within a few minutes or hours.
Something can also slip through for me. Or the technology isn't working as it should. Feel free to contact me again. david@watchdavid.com
Mechanics - Sometimes things can go wrong
Before I ship your order, I carefully inspect each watch for visible defects.
However, should a problem arise, such as a defect during transit, please inform me immediately. I will do everything in my power to find a quick solution and ensure your satisfaction.
My goal is to offer you not only high-quality products but also a first-class shopping experience. I look forward to welcoming you as a satisfied customer!
