Recently fitted with a new ESA 947.111 Swiss quartz movement, it combines iconic vintage design with modern precision.\u003c\/p\u003e\n\u003ch2 style=\"text-align: center;\"\u003eUnusual Dial \u0026amp; Propeller Symbol\u003c\/h2\u003e\n\u003cp\u003eThis version stands out with a modern YEMA logo, a beige straight seconds hand, and a mysterious \u003cstrong\u003epropeller pictogram at 6 o'clock\u003c\/strong\u003e. This symbol is also seen on some Superman models. Despite extensive research, its exact origin remains unknown. It's possible that these dials were specially produced for a diving club or organization.

The crown screws down smoothly and maintains the case’s water resistance in daily use. The watch has been tested under water (non-pressurized) and no leakage was observed when the crown is securely screwed. A pressure test is still recommended before any diving use.\u003c\/p\u003e\n\u003ch2 style=\"text-align: center;\"\u003eSpecifications\u003c\/h2\u003e\n\u003ctable style=\"width: 80%; margin: 20px auto; border-collapse: collapse; border-radius: 10px; overflow: hidden;\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth style=\"padding: 10px; background-color: #e0e0e0;\"\u003eBRAND\u003c\/th\u003e\n\u003ctd style=\"padding: 10px; background-color: #f9f9f9;\"\u003eYema\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"padding: 10px; background-color: #e0e0e0;\"\u003eMODEL\u003c\/th\u003e\n\u003ctd style=\"padding: 10px; background-color: #f9f9f9;\"\u003eNavygraf II Quartz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"padding: 10px; background-color: #e0e0e0;\"\u003eREFERENCE\u003c\/th\u003e\n\u003ctd style=\"padding: 10px; background-color: #f9f9f9;\"\u003eR1 (caseback)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"padding: 10px; background-color: #e0e0e0;\"\u003eMOVEMENT\u003c\/th\u003e\n\u003ctd style=\"padding: 10px; background-color: #f9f9f9;\"\u003eESA 947.111 Quartz, 7 jewels (new aftermarket)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"padding: 10px; background-color: #e0e0e0;\"\u003eCASE MATERIAL\u003c\/th\u003e\n\u003ctd style=\"padding: 10px; background-color: #f9f9f9;\"\u003eStainless steel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"padding: 10px; background-color: #e0e0e0;\"\u003eDIMENSIONS\u003c\/th\u003e\n\u003ctd style=\"padding: 10px; background-color: #f9f9f9;\"\u003e38 mm (bezel), 43 mm (including crown)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"padding: 10px; background-color: #e0e0e0;\"\u003eDIAL\u003c\/th\u003e\n\u003ctd style=\"padding: 10px; background-color: #f9f9f9;\"\u003eMatte black, luminous markers, propeller pictogram at 6 o'clock\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"padding: 10px; background-color: #e0e0e0;\"\u003eHANDS\u003c\/th\u003e\n\u003ctd style=\"padding: 10px; background-color: #f9f9f9;\"\u003eOriginal arrow hands, beige seconds\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"padding: 10px; background-color: #e0e0e0;\"\u003eCRYSTAL\u003c\/th\u003e\n\u003ctd style=\"padding: 10px; background-color: #f9f9f9;\"\u003eAcrylic\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"padding: 10px; background-color: #e0e0e0;\"\u003eBEZEL\u003c\/th\u003e\n\u003ctd style=\"padding: 10px; background-color: #f9f9f9;\"\u003eBakelite, bidirectional, lockable via pusher at 8 o'clock\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"padding: 10px; background-color: #e0e0e0;\"\u003eWATER RESISTANCE\u003c\/th\u003e\n\u003ctd style=\"padding: 10px; background-color: #f9f9f9;\"\u003eOriginal spec 300m (untested for diving)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"padding: 10px; background-color: #e0e0e0;\"\u003eSTRAP\u003c\/th\u003e\n\u003ctd style=\"padding: 10px; background-color: #f9f9f9;\"\u003e19mm Tropic-style rubber (replacement)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"padding: 10px; background-color: #e0e0e0;\"\u003ePRODUCTION PERIOD\u003c\/th\u003e\n\u003ctd style=\"padding: 10px; background-color: #f9f9f9;\"\u003eEarly to mid-1980s\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"padding: 10px; background-color: #e0e0e0;\"\u003eCASEBACK\u003c\/th\u003e\n\u003ctd style=\"padding: 10px; background-color: #f9f9f9;\"\u003eModèle Déposé – R1 – 27 025 6\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2 style=\"text-align: center;\"\u003eCondition \u0026amp; Important Remarks\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eCase in good vintage condition with sharp edges and light wear.\u003c\/li\u003e\n\u003cli\u003eBakelite bezel shows heavy wear and cracking, still fully functional and adds vintage charm.\u003c\/li\u003e\n\u003cli\u003eMovement is brand new, functional and holds excellent time.\u003c\/li\u003e\n\u003cli\u003eBezel lock mechanism works as intended via side pusher.\u003c\/li\u003e\n\u003cli\u003eWater tested under running water; crown seals well when fully screwed.\u003c\/li\u003e\n\u003cli\u003eTropic-style rubber strap is a well-fitted vintage-style replacement.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2 style=\"text-align: center;\"\u003eImportant Notice\u003c\/h2\u003e\n\u003cp\u003e\u003cem\u003e*This vintage diver is functional and water-resistant in standard use, but has not undergone pressure testing.
