The Rolex Milgauss 116400-72400 is a fascinating piece for collectors who appreciate a unique blend of history, engineering, and understated style. Known for its anti-magnetic properties, this reference continues to attract attention even after being discontinued. Let's explore its specifications, real-world performance, and current market positioning.

Key Specifications and Build Quality

This timepiece features a 40mm stainless steel case with a thickness of 13mm, making it comfortable for daily wear while still providing a solid presence. The white dial is paired with a silver Oyster bracelet, and the watch is secured with a folding Oysterclasp. It offers 100 meters of water resistance, which is adequate for swimming and snorkeling but not for professional diving. The dial uses stick hour markers, and the sapphire crystal is highly scratch-resistant, ensuring clarity over the years.

The Heart: Cal.3131 Movement

Inside beats the Cal.3131, a fully automatic mechanical movement with Swiss chronometer certification. This movement is specifically designed to resist magnetic fields up to 1000 gauss, a feature that originated from the original Milgauss models used by scientists and engineers. In practice, the Cal.3131 has proven to be robust and accurate, with daily deviations typically within -2 to +2 seconds under normal conditions. The movement's paramagnetic blue Parachrom hairspring further enhances its resistance to shocks and temperature variations.

Pricing and Market Value

The official retail price for the 116400-72400 was set at ¥60,700 in China, HK$57,500 in Hong Kong, €7,100 in Europe, and $8,710 in the United States. However, since this model has been discontinued, current market prices vary. On the secondary market, you might find examples ranging from $7,500 to $9,500 depending on condition, box and papers, and provenance. Watch enthusiasts often note that this model can be found at a discount compared to its retail price, especially if purchased from certain financial institutions like the Bank of China, which occasionally offer promotions on high-end watches.

Real Owner Experience

A recent buyer shared their journey of acquiring this watch. They received a call about a sale at a company event, and after browsing through several options, they settled on the white-dial Milgauss. The discount was substantial, and despite it being an older, less popular model, the purchase felt rewarding. The owner noted that the daily time error was about four seconds, which they considered acceptable. After six months of occasional wear, the watch still looked relatively new, thanks to its durable bracelet and case. The owner described the watch as 'ordinary but elegant,' perfect for everyday situations where you don't want to be flashy but still appreciate fine craftsmanship.

Pros and Cons

Pros: Unique anti-magnetic feature, timeless design, reliable movement, comfortable size, and potential for good discounts.
Cons: Discontinued, so availability is limited; resale value may not appreciate as much as other Rolex models; the lack of a date function may be a drawback for some.

Should You Buy It in 2026?

If you are a collector looking for a distinctive Rolex with a scientific heritage, the Milgauss 116400-72400 is a worthy addition. It offers excellent value for money, especially if you can find one at a reasonable price. However, if you prioritize investment potential or modern features, you might want to look at other references. Ultimately, the decision comes down to your personal taste and how you plan to use the watch.
