I have a new, never worn, Momentum brand 44mm Torpedo model. It has a stainless steel case, a sapphire crystal, screw down crown, and is water resistant to 200m. This the product description taken from the Momentum website: "The Torpedo is a classic dive watch that can be worn anywhere. It features a 44mm 316L stainless steel case with a brushed finish and 200M water-resistance, perfect for divers or those who spend lots of time in the water. Available with either mineral glass or virtually scratch-proof sapphire crystal. " Momentum is a Canadian Watchmaker based in Vancouver. They produce excellent watches for reasonable prices. The watch has a 2 year warranty that is extendable when you send the watch back to the company for battery changes. The pictures shown are a mix of mine and the company. I prefer EMTs but will take cash. Please text me if you have questions.
