The Heritage Tropic-Proof is a faithful re-release of Alpina’s historic 1965 design, originally engineered to withstand the extreme moisture and climate shifts of transatlantic travel. This revival captures the ultra-robust spirit of the original in a refined 34mm stainless steel case, featuring a high-contrast gloss dial for maximum readability. Combining the tactile charm of a hand-wound mechanical movement with a slim, "tropic-proof" aesthetic, it serves as a durable tribute to the golden age of exploration.
