Introducing the Engineer M Challenger, Ball watch company’s first timepiece powered by a manufacture movement. The Engineer Challenger M is available in stainless steel in either a 40 mm x 13.4 mm case that comes with a black, blue or gray dial, and the option for a leather strap or steel bracelet, or a 43 mm x 13.4 mm case that comes with a black dial and steel bracelet. The entire collection is available on pre-order right now and will be produced in limited numbers. The variants with leather strap are available at a pre-order price of $1,699 (retail $2,899), and the steel bracelet models are $1,799 (retail $2,999). There is also an optional, and very pricey, $85 Nato strap available as an add-on. Although it’s hard to imagine consumers wanting to pay this price for a basic nylon strap.
