The accuracy of timepieces—which was once a matter of life and death—has improved dramatically. While war was one contributing factor, railroads played a significant role even before that. In the UK, as the railway network expanded, each railway company managed its own time based on the time set at its headquarters, and at major transfer stations, the times for each company were displayed. As a result, confusion regarding connections and transfers occurred frequently. In the United States, during the era of single-track operations, collisions and accidents occurred frequently, resulting in the loss of human lives. To reduce accidents, a common standard time was deemed necessary. By 1848, railroad companies had agreed on a standard time based on Greenwich Mean Time, and people began setting their clocks to this time. To honor the original design, only the dial features luminescent markings, while the hands are non-luminescent.\u003c\/p\u003e\n\u003cp\u003eProduct Specifications: Railroad Watch “Railroad”\u003cbr\u003eCITIZEN MIYOTA 12-hour self-winding movement: Made in Japan ・Average daily deviation (at room temperature): -10\/+20 seconds (standard)\u003cbr\u003eWatch Case and Cover: Stainless steel\u003cbr\u003eWater resistance: 3 ATM (3 atmospheres): Suitable for everyday use.\u003cbr\u003eCrystal: Domed sapphire crystal\u003cbr\u003eCase dimensions: Width 46 mm × Height 59.60 mm × Thickness 14.5 mm\u003c\/p\u003e\n\u003cp\u003e### AN5740 — In Stock \u0026amp; Ready to Ship\u003c\/p\u003e\n\u003cp\u003eThe AN5740 Series is currently **in stock and available for immediate worldwide shipping** from our official online store.\u003cbr\u003eA special crowdfunding campaign is also planned for customers in Japan starting in mid-August 2026.\u003cbr\u003e*The CAMPFIRE crowdfunding campaign and its special pricing are available exclusively to customers in Japan.*\u003cbr\u003e\u003c\/p\u003e","brand":"M.R.M.W.","offers":[{"title":"Crazy force Brown Leather strap","offer_id":53880096915640,"sku":"AN5740 railway-1","price":47273.0,"currency_code":"JPY","in_stock":true},{"title":"Green Nylon Nato strap","offer_id":53880096948408,"sku":"AN5740  railway-2","price":47273.0,"currency_code":"JPY","in_stock":false},{"title":"Khaki Nylon Nato strap","offer_id":53880096981176,"sku":"AN5740  railway-3","price":47273.0,"currency_code":"JPY","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0632\/2900\/1912\/files\/0F13D660-C912-4F4F-ACA8-F20B3093971A_1_105_c.jpg?v=1788389853"},{"product_id":"an5740英国軍-ブロードアロー","title":"AN5740   British Army “Broad Arrow”","description":"\u003cp\u003eFeaturing a Japanese-made mechanical movement, stainless steel case, stainless steel bezel, and sapphire crystal—now finally available to the general public!
