We’ve fitted this pocket watch with a specialized case to create a timepiece that can be enjoyed as either a wristwatch or a pocket watch. (Design patent registered)\u003c\/p\u003e\n\u003cp\u003eEven today, there are products that wrap a pocket watch in a leather cover to turn it into a wristwatch. However, these inevitably end up being large and bulky. The strap cover hides the pocket watch’s form, compromising its original shape and atmosphere. While the method of welding on lugs is certainly simple, it means you can never enjoy it as a pocket watch again. With this product, you can enjoy it both as an authentic pocket watch and as a wristwatch. Unlike the AN5740 with its black dial, this is a reissue of a dial considered a “legend” even among collectors, with only a very small number still in existence. It is extremely rare, and it seems certain that it was issued exclusively to a select few pilots embarking on long-range strategic bombing missions.\u003c\/p\u003e\n\u003cp\u003eThe large dial features a black-and-white color scheme that ensures high visibility and allows for intuitive distinction between AM and PM, making it a design-wise excellent piece.\u003c\/p\u003e\n\u003cp\u003eIt has been resized (reducing the diameter by approximately 5 mm to 46 mm) to make it more comfortable to wear as a wristwatch. It has also been reissued as a battery-powered quartz watch. Thanks to the large dial, the time is easy to read even on a 24-hour watch.\u003c\/p\u003e\n\u003cp\u003eThe meaning of “B.J.B.” inscribed on the dial remains unclear. One theory suggests it refers to the “Berlin-Japan Bomber,” a strategic bomber unit.\u003c\/p\u003e\n\u003cp\u003eProduct Specifications AN5740 24H Night \u0026amp; Day\u003c\/p\u003e\n\u003cp\u003e24-hour quartz movement: Manufactured by Ronda, Switzerland ・Accuracy (at room temperature): Average monthly deviation of 15 seconds (standard)\u003c\/p\u003e\n\u003cp\u003eWatch Case and Cover: Stainless Steel\u003c\/p\u003e\n\u003cp\u003eWater Resistance: 3 ATM (3 atmospheres) – suitable for everyday use.\u003c\/p\u003e\n\u003cp\u003eCrystal: Domed sapphire crystal\u003c\/p\u003e\n\u003cp\u003eBattery: Silver oxide battery SR920SW • Battery Life: Approximately 2 years\u003c\/p\u003e\n\u003cp\u003eWatch Case Dimensions: Width 46 mm × Height 56 mm × Thickness 16 mm\u003c\/p\u003e","brand":"M.R.M.W.","offers":[{"title":"Crazy force Brown letaher step","offer_id":53880106221752,"sku":"AN5740-24ND-1","price":235.0,"currency_code":"USD","in_stock":true},{"title":"Green Nylon Nato Strap","offer_id":53880106254520,"sku":"AN5740-24ND-2","price":235.0,"currency_code":"USD","in_stock":false},{"title":"Khaki Nylon Nato Strap","offer_id":53880106287288,"sku":"AN5740-24ND-3","price":235.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0632\/2900\/1912\/files\/DCB647E4-02BE-4848-B1A1-860B51A2DDA7_1_105_c.jpg?v=1788390285","url":"https:\/\/mrmw.jp\/en-us\/products\/an5740-24nd","provider":"M.R.M.W Montre Roroi Military Watch","version":"1.0","type":"link"}
