This versatile timepiece transitions seamlessly from formal occasions to everyday wear. Driven by an automatic BALL caliber RR1101 movement, this watch delivers reliable accuracy and smooth mechanical performance. The pristine white enamel dial showcases classic proportions and exceptional readability, enhanced by 15 micro gas tubes positioned on the hour and minute hands plus dial for dependable night visibility. The 40mm stainless steel case maintains refined proportions at just 12mm in height, striking the perfect balance between presence and wearability. The 30m water resistance accommodates daily water exposure, while 5,000Gs shock resistance protects the movement from impacts. A screwed-in crown ensures secure operation and water-sealing integrity. The anti-reflective sapphire crystal provides crystal-clear dial visibility, while the transparent sapphire caseback showcases the mechanical beauty within. Choose between a stainless steel bracelet with folding buckle for professional versatility or a crocodile leather strap with buckle for refined elegance—both options deliver comfort and durability. With a 20mm lug width and 46mm lug-to-lug distance, this timepiece accommodates diverse wrist sizes while maintaining balanced aesthetics. The Trainmaster collection embodies Ball's commitment to creating watches that honor horological heritage while meeting the precision standards of modern professionals. A timeless instrument for those who appreciate understated sophistication.[\/product_description]\u003cbr\u003e[unique_description_1]\u003cli\u003e\n\u003cb\u003eCollection: \u003c\/b\u003eEngineer II\u003c\/li\u003e\u003cli\u003e\n\u003cb\u003eGender: \u003c\/b\u003eMen\u003c\/li\u003e\u003cli\u003e\n\u003cb\u003eDial Color: \u003c\/b\u003eWhite\u003c\/li\u003e\u003cli\u003e\n\u003cb\u003eStrap Color: \u003c\/b\u003eSilver\u003c\/li\u003e\u003cli\u003e\n\u003cb\u003eStrap Material: \u003c\/b\u003eStainless Steel\u003c\/li\u003e\u003cli\u003e\n\u003cb\u003eStrap Type: \u003c\/b\u003eBracelet\u003c\/li\u003e\u003cli\u003e\n\u003cb\u003eStrap Clasp Material: \u003c\/b\u003eFolding Buckle\u003c\/li\u003e\u003cli\u003e\n\u003cb\u003eStrap Clasp Type: \u003c\/b\u003e20\u003c\/li\u003e\u003cli\u003e\n\u003cb\u003eLug Width (Mm): \u003c\/b\u003e20\u003c\/li\u003e\u003cli\u003e\n\u003cb\u003eMovement: \u003c\/b\u003eAutomatic\u003c\/li\u003e\u003cli\u003e\n\u003cb\u003eCaliber: \u003c\/b\u003eRR1807\u003c\/li\u003e\u003cli\u003e\n\u003cb\u003eCase Shape: \u003c\/b\u003eRound\u003c\/li\u003e\u003cli\u003e\n\u003cb\u003eLug To Lug (Mm): \u003c\/b\u003e46.6\u003c\/li\u003e\u003cli\u003e\n\u003cb\u003eCase Material: \u003c\/b\u003eStainless Steel\u003c\/li\u003e\u003cli\u003e\n\u003cb\u003eCase Diameter (Mm): \u003c\/b\u003e40\u003c\/li\u003e\u003cli\u003e\n\u003cb\u003eCase Height (Mm): \u003c\/b\u003e13.4\u003c\/li\u003e\u003cli\u003e\n\u003cb\u003eCaseback: \u003c\/b\u003eTransparent Case Back\u003c\/li\u003e\u003cli\u003e\n\u003cb\u003eCrystal Type: \u003c\/b\u003eAnti-reflective sapphire\u003c\/li\u003e\u003cli\u003e\n\u003cb\u003eCrown: \u003c\/b\u003eScrewed\u003c\/li\u003e\u003cli\u003e\n\u003cb\u003eWeiht (G): \u003c\/b\u003e145\u003c\/li\u003e\u003cli\u003e\n\u003cb\u003eAnti-Magnetism: \u003c\/b\u003e4,800A\/m\u003c\/li\u003e\u003cli\u003e\n\u003cb\u003eWater Resistance: \u003c\/b\u003e100 meters\u003c\/li\u003e[\/unique_description_1]\u003cbr\u003e[unique_description_2]\u003cli\u003e\n\u003cb\u003eMicro Gas Tubes: \u003c\/b\u003e15 micro gas tubes on hour and minute hands and dial for night reading capability\u003c\/li\u003e\u003cli\u003e\n\u003cb\u003eFunctions: \u003c\/b\u003eHours, minutes \u0026amp; sweep seconds, 5,000Gs shock resistance\u003c\/li\u003e\u003cli\u003e\n\u003cb\u003eCertified: \u003c\/b\u003eChronometer certified COSC\u003c\/li\u003e[\/unique_description_2]","brand":"Ball","offers":[{"title":"Default Title","offer_id":55336571076930,"sku":"NM3888D-S9J-WH","price":1949.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0789\/4250\/3234\/files\/NM3888D-S9J-WH.jpg?v=1785172607","url":"https:\/\/diamondsoflondon.com\/products\/ball-trainmaster-standard-time-40mm-watch-nm3888d-s9j-wh","provider":"Diamonds of london Tx","version":"1.0","type":"link"}
