Patek Philippe Ref. 5975: The 'Chin' Tachymeter Debate

Key Points from the Discussion

• The 'chin' on the tachymeter scale, where it extends around the date circle at the 6 o'clock position, is a notable design element of the Ref. 5975. This feature is a point of discussion among collectors, with some valuing it for its shorter production period and theoretically more accurate tachymeter reading, while others find its aesthetic unconventional.
• Some collectors, like 'cts', prefer the 'chin' design as it allows for a complete and visible tachymeter scale, avoiding any partial absence of the markings.
• The Patek Philippe Ref. 5975 is considered an iconic reference for many collectors, representing a pinnacle of ownership within the brand's offerings.
• The original poster's alma mater is the HKU Faculty of Medicine, though the wrist shots were taken at the main campus, which was primarily used for examinations.
• A fellow forum member shared a similar experience of teaching HKU masters students, noting the elegance of the old main building and the challenges of remote teaching compared to on-campus interaction.
