The display incorporates an outsize date, a full perpetual calendar function, a moon-phase display, a day\/night indicator, a day-of-week display, and a zero-reset mechanism — all rendered with the discipline of proportion that defines A. Lange \u0026amp; Söhne's approach to dial architecture.\u003c\/p\u003e\u003cp\u003ePowering the watch is the self-winding caliber L922.1, a movement composed of 478 individual parts oscillating at 21,600 semi-oscillations per hour (3.0 Hz) and delivering a power reserve of 46 hours. The movement designation and its 478-component count speak to the engineering depth concentrated within the 38.5mm footprint.\u003c\/p\u003e\u003cp\u003eThe watch is worn on a dark blue alligator leather strap — sourced from farmed alligator mississippiensis in full compliance with CITES Appendix II regulations — secured by an 18-carat white gold prong buckle that echoes the case material throughout the piece.\u003c\/p\u003e","brand":"It's That Time","offers":[{"title":"Default Title","offer_id":49919849562341,"sku":null,"price":115000.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0645\/5600\/7653\/files\/A-Lange-Sohne-310.028-E-Langematik-Perpetual-Blue-Dial-Alligator-Strap.jpg?v=1782915744","url":"https:\/\/itsthattimenyc.com\/products\/a-lange-sohne-310-028-e-langematik-perpetual-blue-dial-alligator-strap","provider":"It's That Time ","version":"1.0","type":"link"}
