This week’s Watch of the Week features the Rolex Oyster Perpetual 36 (126000), one of the collection’s most popular references. ⁠ ⁠ With no date window, rotating bezel, or additional complications, the Oyster Perpetual focuses on the fundamentals of mechanical watchmaking. Its straightforward design and variety of configurations have made it a popular choice among both first-time Rolex buyers and experienced collectors.⁠ ⁠ Inside the Oyster Perpetual 36 is Rolex's in-house Calibre 3230 automatic movement, offering approximately 70 hours of power reserve. It features the Chronergy escapement for improved efficiency, a blue Parachrom hairspring for resistance to magnetic fields and temperature changes, and Paraflex shock absorbers. The movement carries Rolex's Superlative Chronometer certification, with precision tested to within minus two to plus two seconds per day after casing. These features give the Oyster Perpetual the same level of mechanical attention found in many of the brand's more complicated models.⁠ ⁠ Read more in this week’s blog at the link in our bio.
