All about the Circula ProTrail Grey New
Field watches were originally designed for military use and specifically tailored to the requirements of ground troops. Their main features are uncompromising functionality and exceptional robustness, making them ideal for outdoor activities such as hiking, swimming, or mountain biking.
Compared to pilot or diver watches, field watches do not feature an elaborate bezel. Classic models are often simple three-hand watches without a date display, but with a practical 24-hour scale on the dial.
ProTrail/ProFlight – Update
Case and steel bracelet updates:
- 1 mm flatter and more ergonomically shaped with unchanged water resistance of 150m and 80,000 A/m antimagnetism
- new, grippier crown for ProTrail
- slight curve between the lugs, so that canvas straps and the new Pro steel bracelet fit seamlessly with the case
- new stainless steel bracelet with quick adjustment in the clasp
Our Circula ProTrail is additionally anti-magnetic up to 80,000 A/m, thanks to a special soft iron cage. This makes it impervious to magnetic fields from smartphones, laptops, and other electronic devices that could affect its accuracy. By using Super-LumiNova® on the hands and numbers/indices, the time can be easily read even in the dark.
The durable canvas strap is a custom-made product that ensures a secure fit on the wrist and a comfortable feel. Another special feature of the Circula Field Watch is the 316L stainless steel case, which is extremely robust and scratch-resistant up to 1,200 Vickers due to a special surface treatment.
The Circula Field Watch is also perfectly suited for use in water. It is water-resistant up to 15 ATM and equipped with a screw-down crown. This robust Field Watch from Circula is the perfect companion for any adventure!

The ProTrail is an authentic field watch, distinguished by its robustness, functionality, and high-quality craftsmanship. Its carefully hand-sandblasted stainless steel case protects the precise Swiss movement and is anti-magnetic up to 80,000 A/m, making it particularly resistant to magnetic fields. Thanks to the scratch-resistant sapphire crystal and a special surface treatment of the case, the watch offers outstanding durability and resilience.
The ProTrail was developed in collaboration with over 6,500 votes from the global watch community, thus offering the highest quality and functionality. A special variant of the watch is the Black Old Radium LE, which is limited to 99 pieces and features a unique dial design and a black-coated case. The Micro Praha LE, another limited version of 50 pieces, was created in collaboration with a watch club from Prague and stands out with its exclusive design.
This field watch from the traditional Pforzheim brand stands for quality Made in Germany and is equipped with the Swiss automatic movement caliber Sellita SW200-1 Elaboré.

The hands and indices are equipped with Swiss Super-LumiNova®, ensuring good readability in poor light conditions. With a water resistance of up to 150 meters and a screw-down crown that also glows, the ProTrail is well-equipped for various adventures.

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!
