All about the OLLECH & WAJS OW P-104 SELECTRON
The Return of the Selectron – The New OW P-104 Selectron
With great pride, Ollech & Wajs brings the legendary Selectron designation back into the collection – in the form of the new OW P-104 Selectron. This model incorporates design features of later Selectron watches, especially those of the "Selectron Calculator" Ref. 004, released in 1969. This historic watch was supplied by Ollech & Wajs to General Electric Co. at the time and was specially developed for their aerospace engineers and test pilots.
Precision Meets Tradition
In keeping with its historical predecessor, the new OW P-104 Selectron is also equipped with a bidirectional bezel featuring logarithmic scales. This allows numerous mathematical calculations to be performed with just one rotation – faster than any so-called smartwatch. Furthermore, it requires no battery and remains fully functional underwater up to 300 meters. A truly intelligent solution!
The high-contrast dial, inspired by the minimalist instrumentation of a cockpit, guarantees excellent legibility. The ivory-colored indices and the hands coated with luminous orange Super-LumiNova® ensure optimal visibility even in low light conditions. The design is completed by an RAF regimental strap, a tribute to the close connection of Selectron watches to military aviation.
Swiss Precision Within
The watch is powered by the Soprod Newton Precision P092, an outstanding automatic movement specifically modified to OW's specifications. This caliber is independently tested for its reliability and robustness at the renowned Laboratoire Dubois in Chaux-de-Fonds. It has been adjusted in five positions, features a distinctive OW-Zürich-1956 engraving on the nickel-plated movement plate, and is equipped with a specially designed rotor in the shape of the OW logo.
Limited Edition with COSC Certification
To celebrate the return of the Selectron, Ollech & Wajs is releasing an exclusive special edition of only 56 numbered pieces. Each model in this limited series is marked by an individual engraving on the crown (number/56) and also features an official COSC certification from the Contrôle Officiel Suisse des Chronomètres (COSC). This confirms the highest level of accuracy and underscores the exceptional quality of this timepiece.
A Watch for True Connoisseurs
The OW P-104 Selectron comes with a regimental-style RAF nylon strap. Additionally, an OW S-Type "Beads of Rice" metal bracelet and a handcrafted black leather strap are available as accessories.
While digital technologies are increasingly replacing traditional instruments, the OW P-104 Selectron proves that slide rule watches are far from obsolete. This model combines mechanical intelligence with timeless elegance and makes a powerful statement against digital change.

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!
