Bertucci A-5S Ballista Field Watch with Swiss Micro Tube Illumination #13550

The A-5S Ballista™ watch is a professional tactical field watch. It comes with a 45mm diameter black ion-plated stainless steel case with an easy-to-read black aviator dial with constant glowing tritium tube on the hands and hour markers. In addition, SuperLuminova is also used in the triangle shaped hour markers. A sapphire crystal guards against scratches out in the field. Inside is a Swiss made, gold plated all-metal precision quartz analog movement with 5 jewels. An offset screw down crown is at 4:00. Includes a screw-in case back, integrated unbreakable stainless steel lug bars, and a long lasting, comfortable DX3™ one piece nylon strap.

A 10-year lithium cell battery powers the movement. So, it will be years before you need a new battery. The watch is also water resistant to 200 meters.

Accurate & Tough	July 20, 2020
Reviewer: Chris from Peoria, AZ United States

I bought this watch with some specific requirements. I need; a watch to withstand rough abuse, a legible face I can read without glasses, and long battery life. The specs meet all of these requirements. Only time will tell if the battery lasts 10 years as advertised.

So far I have used the watch while mountain biking, shooting, and during landscape construction in my yard. The watch is quite accurate - a few seconds fast over 3 weeks time. The case coating and movement have taken the abuse with no signs of wear yet.

Notably, the watch and strap are very large. Not ridiculous large like some watches but it covers the top of my medium size wrist completely. I have 7 inch wrists. The watch is just the right size so that it does not overhang or get in my way while working.
