Its three-window Day-Date-Month display is the picture of simplicity and easy viewing. While other brands force users to strain their eyes at microscopic sub-dial indications, Patek places all pertinent info within easy view. The 5135R is a classical Patek Philippe tonneau that wears like a modern watch. Its size and wrist presence receive a huge boost from broad-shouldered proportions that stretch 51mm from lug-to-lug. This watch is the cure for "petite Patek" syndrome. To those who admire the heritage and quality of Patek Philippe watches but hesitate to purchase one of the many sub-40mm models; your watch has arrived. The Gondolo 5135R wears much like a 45mm round watch (such as a Panerai Radiomir), and it never threatens to disappear on the sprawling real estate of an 8" wrist. At the same time, a flat profile and rounded case flanks ensure that the Gondolo 5135R slips easily under long sleeves in general and cuffs in particular. Inside, a Patek Philippe annual calendar is driven by the classic Patek Philippe in-house cal. 324 movement. Its Patek-signature Gyromax balance, Geneva Seal luster, and robust engineering uphold the legend of Patek's craftsmanship. If you own this watch, you *must* own a loupe. Examining this movement under 20X magnification only to see your reflection in a screw head is the stuff of watch nerd dreams. Available from thewatchbox.com with full Patek Philippe factory boxes, manuals, accessories, and documents of provenance, this Patek Philippe Gondolo 5135R is the ideal point of entry into the storied world of Patek complications.
