All about the COSC Certification for Ollech & Wajs Watches
What COSC means.
Independent Testing: The organization is a non-profit, independent body that conducts rigorous tests.
High Accuracy: Only movements that meet strict criteria (e.g., a daily rate deviation between -4 and +6 seconds) receive certification.
Testing Process: The tests last 15 days and include tests in various positions and at different temperatures.
Scope: Certification is exclusively limited to "Swiss Made" movements.
Difference to Chronograph: A chronograph is a function (stopwatch), while a chronometer is an extremely precise timepiece that requires COSC certification to bear the title.
What COSC certification means.
- Increase in Value: A COSC certification increases the value and prestige of a watch.
- Guarantee of Reliability: Buyers can rely on the watch possessing demonstrably high technical quality and reliability.

FAQs
About David from WATCHDAVID
Behind WATCHDAVID.SHOP, I, David Drilling, stand as a true watch enthusiast, watch photographer, and independent tester. Since 2018, I have been providing honest wear reports on my channels. In my shop, I exclusively sell watches whose quality and history I have personally verified. No anonymous mass-produced goods, but personal expertise.
Shipping & No Import Charges
Shipping within Germany and the EU is completely free for you and fully insured via DHL or FedEx Express. Important for you: There are guaranteed to be no import duties, taxes or hidden fees. The exact delivery time for your model will always be transparently displayed directly above the "Buy" button.
Cancellations & Free Returns
You can easily cancel your purchase within 14 days. Unlike other retailers, I will cover the full cost of your return shipping within the EU. Simply send me a short email to david@watchdavid.com and I will send you your free DHL return label. It doesn't get any more risk-free than that.
Authenticity & Condition of the Watches
I guarantee you 100% that all watches offered are unworn, brand new original goods. In the shop, I strictly differentiate between regular new goods directly from the manufacturer and exclusive photo watches. Photo watches are models that I have used for my videos or photos, or that come from a return. I sell them absolutely honestly as used and significantly reduced – but the full manufacturer's warranty only begins on the day of your purchase!
Warranty & David's "All-Round Carefree Service"
Every watch comes with the full, international manufacturer's warranty (at least 2 years). In the event of a warranty claim, you'll have absolutely no stress: I'll handle all communication with the brand and organize insured round-trip shipping for you. Even after the warranty period expires, I remain your personal point of contact for service inquiries.
Quality Control
Mechanical watches are fascinating masterpieces. Before dispatch, each watch undergoes a thorough optical and mechanical final inspection. Should a problem ever arise despite our secure transport protection, please inform me immediately by email. I will promptly arrange for a quick, uncomplicated replacement.
