All about the OLLECH & WAJS OW Navichron
The OW NAVICHRON comes with an aged natural leather and linen vintage racing strap, handcrafted by one of Italy’s finest tanneries. The luxurious strap is finished with a brushed stainless-steel pin buckle, signed ‘OWZ 1956’.
The OW NAVICHRON S is presented on the OW S-Type Mark II bracelet, inspired by many Ollech & Wajs models from the 1960s. Its links are individually milled from a solid block of 316L stainless steel, before being carefully brushed, assembled by hand and screwed. This process prevents the usual stretching common in pressed steel bracelets, ensuring durability and comfort for the wearer. Its double-lock deployant clasp prevents accidental opening.
OLLECH & WAJS OW Navichron
Today’s OW Navichron is powered by a Valjoux 7753-based two-register chronograph. It follows a long lineage of Valjoux chronographs, with highly regarded historical references such as the V72, V92, V7730, V7733, and V7750. OW has developed its own precision rating, reserved only for the highest quality movements. We start with a Valjoux 7753 in a brutal matte finish, which we then reassemble with our own machined rotor, bearing the famous OW propeller monogram. We engrave the main plate with ‘Ollech & Wajs Zurich 1956’ before removing the hour counter. We then reassemble, regulate, and test its precision in five positions, as well as its duration.
The OW Navichron maintains a 12-hour gliding bezel, allowing travelers to tell the time in different zones. It is also a highly capable professional diver’s watch, featuring a 20-minute dive scale on its bezel, like the original Navichron of 1967. It boasts a specially reinforced case, extra-thick sapphire crystal, and unique four-gasket pushers, capable of withstanding pressures exceeding 50 ATM. Its markings and hands are equipped with Super-LumiNova®, ensuring maximum visibility in all conditions, above and below the surface.

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!
