After that collision, renowned jeweller Webb C. Ball was appointed Chief Time Inspector to investigate the accident's timekeeping issues. Ball then formulated a new timekeeping system for the railroad industry, revolutionising timekeeping (in the industry) and thus making train travel significantly safer for passengers and employees. The watches employees used were certified and issued by Ball, leading to the birth of the legendary company known today as Ball Watch Co.

Unveiling the newest Engineer III Marvelight, Ball has introduced their new COSC movement in one of their most popular Engineer III models, the Marvelight. The newest Engineer III Marvelight measures smaller than previous models at 38mm in diameter, 11.5mm in height and 44mm lug-to-lug. The dimensions help the Marvelight wear superbly well on any wrist. Further, it features a screwed-in crown, making it 100m water-resistant.

What makes this limited edition Engineer III Marvelight unique is the use of the premium 904L stainless steel. This steel has been used primarily by the big "R" company for decades. 904L stainless steel is unlike any other steel. Due to its extra amounts of chromium, molybdenum, nickel and copper, 904L steel features superior resistance to corrosion, rust and acids. While its unique hardness allows it to withstand extreme conditions, it requires special machinery and production processes to be shaped, which is why it is not as commonly used. Visually, 904L stainless steel has an exceptionally high polish compared to 316L steel and ages exquisitely well.

Moving on to the dial, the new Engineer III Chronometer sticks to its DNA from the earlier version but comes in a flamboyant colour. The sunburst dial has a smokey green effect, where it graduates and gets darker towards the periphery. The eleven indices with "micro" gas tubes on the dial are thick, filling up the dial nicely while helping legibility when reading the time. Each tube illuminate a different colour, giving it a unique rainbow glow in the dark. The sword hands glow yellow as ensuring time keeping capabilities in the dark. Couple this with their signature seconds hand with Ball's "RR" symbol as a counterweight on the other end. Topping things off for the dial, the Engineer III Marvelight has a cyclops flat sapphire crystal with an anti-reflective coating underneath.

The Ball Engineer III Marvelight Chronometer Green NL9616C-S1C-GR is powered by the Ball calibre RR1101-C. Renowned for its precision and accuracy, a Swiss-made automatic BALL RR1101-C movement drives the timepiece's essential hours, minutes, sweep seconds and date functions. This calibre complies with the criteria of the prestigious chronometer standard authorized by the Official Swiss Chronometer Testing Institute (COSC), guaranteeing Swiss accuracy and reliability. The movement is hooded by a screw-in caseback that displays Ball's iconic emblem with essential information engraved at the periphery.

The new Marvelight's 904L steel bracelet runs alongside the show's star and is done with a nice mixture of polished and satin-brushed finishing. The bracelet gets a nice taper from 20mm to 18mm at the clasp area, making it more wearable. It further features a double-sided locking clasp system, making the bracelet appear more streamlined when worn.

Limited to 1000 pieces, the Ball Engineer III Marvelight Chronometer Green NL9616C-S1C-GR is certainly for someone who appreciates fine watchmaking that packs reliability and value from a respected watch company. The use of the premium 904L stainless steel gives the watch an exceptional glow while making it tougher and more corrosion resistant at the same time. The watch exhibits exceptional value given that it has a 28,800bph modified ETA movement. The one-of-a-kind sunburst fumé green dial, mesmerising self-illuminating rainbow tritium tubes, and exceptional case finishing make the Marvelight high up in the value-for-money chart. We cannot find a reason to not like this watch.
