The Vertex M100A is a contemporary automatic watch inspired by the brand’s wartime WWW Cal 59, not a reissue of the original military watch. Its 40 mm brushed-steel case, raised luminous dial and 100 m manufacturer-rated water resistance give it a practical, military-influenced specification; the UK product page lists it at £2,500 including VAT. That price buys a three-strap package and a five-year global guarantee, but the available evidence does not establish real-world accuracy, comfort, lume duration or water performance.
What is the Vertex M100A?
The M100A is the brushed 316L stainless-steel version of Vertex’s modern M100 series. Vertex calls it “the ultimate homage to the legendary Vertex WWW Cal 59,” framing the design as a tribute to its Second World War predecessor rather than a continuation of the same watch. The M100 is made with contemporary watchmaking technology and is best understood as a new automatic watch with a historical design reference.
The wartime WWW watches are commonly known as the “Dirty Dozen”: 12 models supplied by 12 companies to meet British Ministry of Defence requirements. Monochrome Watches reported in 2019 that about 150,000 WWW watches were supplied between May and December 1945, with Vertex making approximately 15,000. Those are approximate figures from secondary coverage, not an official production register. Monochrome Watches’ historical account also discusses the modern watch as an interpretation, rather than a proper reissue.
How big is the Vertex M100?
Vertex advertises the M100A at 40 mm in diameter, 48.5 mm lug-to-lug, and 12.2 mm thick, with 20 mm between the lugs. These are manufacturer-stated dimensions, not independent measurements. The 48.5 mm lug-to-lug figure is especially useful when judging fit: it describes the span across the wrist more directly than the 40 mm diameter alone. Compare that length with a watch you already find comfortable, and consider the case thickness if you wear close-fitting cuffs.

What does the M100A look like, and what are its key features?
The M100A pairs a brushed-steel case with a military-style dial and small seconds. Its most distinctive detail is the moulded dial, which carries C3 X1 Super-LumiNova, while a double-domed sapphire box crystal with anti-reflective treatment sits above it. The raised dial construction gives the watch a more dimensional look than a conventional flat printed dial. Vertex specifies these materials and features; no independent lume-duration or visibility testing is established here.
The watch has a locking, screw-in crown and a stated water-resistance rating of 100 m. That is the manufacturer’s rating, not a result from an independent pressure test, so it should not be read as proof of performance under particular conditions.

What movement is in the Vertex M100A?
Vertex specifies an automatic, 31-jewel Sellita SW260-1 Top Execution movement. The available product information does not establish independently measured accuracy or a timing result for this individual model. Buyers who prioritize timekeeping should therefore treat the movement identification as a specification, not a performance guarantee.
What comes with the Vertex M100A?
The advertised set includes three straps: a black leather strap, an Admiralty Grey NATO strap and an additional Vertex NATO strap. Vertex also lists a Peli-style case and a five-year global guarantee. These are details of the manufacturer’s stated package and warranty; confirm the current set contents and applicable guarantee terms with the seller before ordering.

What is the difference between the Vertex M100A and M100AC?
The M100A is the brushed-steel version covered in this review. Vertex describes the M100AC as a DLC-coated version of the M100A. The series page establishes that finish distinction, but the available information does not establish a difference in dimensions, included straps or regional price. Check the live product listing for the exact package and price in your market before comparing the two.
Choose between them primarily on appearance: brushed steel for a conventional metal finish, or the coated look of the M100AC. There is not enough evidence here to make claims about the coating’s scratch resistance or long-term durability.

Is the Vertex M100 worth the price?
Vertex’s UK product page lists the M100A at £2,500 including UK VAT. Price and availability can change, and this is a UK figure rather than a universal price. At that level, the case for the watch rests on its specific heritage connection, raised luminous dial, sapphire crystal, automatic movement, three-strap package and five-year guarantee—not on demonstrated timing or water-resistance results. Check Vertex’s current M100A page for the latest price, availability, shipping and return terms applicable to your location.
The M100A makes the most sense for someone who values the Vertex design lineage and wants a modern automatic watch with military styling. If the historical connection is incidental, or if you require independently verified accuracy or water performance, the stated specifications alone do not settle whether it is worth the outlay.
