The two-tone silver mirror-finish \"Doctor's\" dial, executed in Art Deco styling, is exceptionally beautiful and remarkably well preserved. The greatest highlight of this piece is the condition of its original fixed leather strap with the original buckle. It appears the watch may have been tried on only a couple of times over the course of a century. The movement screws have never been fitted with a screwdriver.\u003cspan class=\"PDq2pG_selectionAnchor\" aria-hidden=\"true\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp data-end=\"1219\" data-start=\"487\"\u003eOn the caseback, we can see a \u003cstrong data-end=\"549\" data-start=\"517\"\u003ePoinçon de Maître Geneva Key\u003c\/strong\u003e, which indicates that the case was produced in Geneva. Since 1934, it was mandatory for all Geneva-based case makers to use a maker's hallmark. Some manufacturers, however, began using them well over a decade earlier. The number inside the key leads directly to the maker of the gold watch case. In this case, the number \"10\" inside the \u003cstrong\u003eGeneva Key \u003c\/strong\u003ecorresponds to \u003cstrong data-end=\"927\" data-start=\"917\"\u003eMeylan\u003c\/strong\u003e, also known as\u003cstrong\u003e \u003c\/strong\u003eUFSB.

The company's address was 4 Rue Winkelried, Geneva.

His name became permanently associated with one of the most unusual episodes in the company's early history: the 1938 burglary of Rolex's Geneva workshops, during which solid gold and platinum watch cases worth approximately 100,000 Swiss francs were stolen. Meylan later confessed to participating in the theft alongside French criminal Yves Le Gallou, admitting that he had melted down most of the stolen cases in his own factory to disguise their origin. Acting on his testimony, Swiss authorities recovered nearly 15 kilograms of buried gold and platinum watch cases and components in the Jura Mountains. The company Robert Meylan, then located at 78 Rue de Lausanne, Geneva, ceased operations and called in creditors in September 1939.\u003c\/p\u003e\n\u003ch3 data-end=\"2568\" data-start=\"2547\" data-section-id=\"16e7wj3\"\u003eRolesor Trademark\u003c\/h3\u003e\n\u003cp data-end=\"2714\" data-start=\"2570\"\u003eThe term \u003cstrong data-end=\"2590\" data-start=\"2579\"\u003eRolesor\u003c\/strong\u003e is a registered trademark (originally filed in \u003cstrong data-end=\"2646\" data-start=\"2638\"\u003e1933\u003c\/strong\u003e).

In November 1912, the registered name of the Aegler company was changed, as shown in the published announcement, to \"Les Fils de Jean Aegler, Fabrique de Montres Rebberg, Final \u0026amp; Rolex\". In 1913, Aegler registered Rolex as a trademark for the manufacture of watches and watch parts. From this point onward, the histories of Wilsdorf \u0026amp; Davis, Aegler, and Rolex become virtually impossible to separate using publicly available information. It is nevertheless clear that Aegler and Rolex remained separate companies, and that Aegler continued supplying watches to companies other than Rolex throughout the 1930s. Over time, however, their relationship became increasingly close, with several changes to the companies' legal names and corporate structures.\u003c\/p\u003e\n\u003cp data-end=\"5236\" data-start=\"4877\"\u003eIn September 1936, the company adopted the corporate name \"Manufacture des Montres Rolex, Aegler Société Anonyme\" and thereafter produced watches exclusively for Rolex, operating as a partner company within the Rolex organization until 31 December 2004. The Borer family eventually decided to sell the Aegler company, and it was acquired by Rolex.\u003c\/p\u003e\n\u003ch3 data-end=\"5254\" data-start=\"5238\" data-section-id=\"756yk\"\u003eThe Movement\u003c\/h3\u003e\n\u003cp data-end=\"5639\" data-start=\"5256\"\u003eWe do not know the exact caliber fitted to this watch, but it unquestionably represents one of the highest-quality movements produced during its era. \u003cstrong data-end=\"5423\" data-start=\"5406\"\u003e\"Ultra Prima\"\u003c\/strong\u003e was Aegler's highest movement grade, as indicated on the lower wheel train.
