The sizes differ in lug width and movement calibre; the available official specifications do not establish how either watch fits or feels on the wrist. For the specific 39 mm beige-dial steel-bracelet model, TUDOR lists reference M79950-0008.
What changes between the 36 mm and 39 mm Ranger?
TUDOR’s 2025 Ranger press kit specifies both case sizes with satin-finished steel cases, while assigning different calibres and lug widths to each. The current product page provides additional case details for the 39 mm beige-dial reference.
| Specification | 36 mm Ranger | 39 mm beige Ranger, M79950-0008 |
|---|---|---|
| Case diameter | 36 mm (TUDOR 2025 press kit) | 39 mm (TUDOR product page) |
| Case material and finish | Satin-finished steel (TUDOR 2025 press kit) | Satin-finished steel (TUDOR product page) |
| Case thickness | Not stated in the cited TUDOR materials | 12.0 mm (TUDOR product page) |
| Lug width | 19 mm (TUDOR 2025 press kit) | 20 mm (TUDOR product page) |
| Movement | Manufacture Calibre MT5400 (TUDOR 2025 press kit) | Manufacture Calibre MT5402, COSC-certified (TUDOR product page) |
| Power reserve | Approximately 70 hours (TUDOR 2025 press kit) | Approximately 70 hours (TUDOR product page) |
| Water resistance | 100 m (TUDOR 2025 press kit) | 100 m (TUDOR product page) |
The different calibre numbers correspond to the two case-size specifications; the available sources do not establish a performance advantage for one over the other. The 39 mm reference page also specifies a smooth satin-brushed bezel, domed sapphire crystal and a three-link steel bracelet with TUDOR “T-fit” safety catch.
Beige or black: how TUDOR describes the dials
The color wording depends on the source. The current product heading for reference M79950-0008 calls its dial beige, while the product copy describes it as matt “Dune white.” TUDOR’s 2025 press kit lists grained matt black and “Dune white” dial options. These labels identify the brand’s offered finishes; they do not amount to a real-world comparison of color or legibility in different lighting.

The cited 39 mm beige-dial product page specifies a steel bracelet. TUDOR’s 2025 press kit also presents fabric-strap configurations among the collection options, but the cited materials do not establish every size-and-dial combination or strap pairing. Check the exact reference before assuming a particular configuration is available. If choosing a replacement strap, match it to the watch’s lug width—19 mm for the 36 mm specification or 20 mm for the cited 39 mm model—and confirm the attachment system for that reference.
Which size should you choose?
The 39 mm case is 3 mm wider than the 36 mm version, and its stated lug width is 1 mm greater. Those dimensions can help narrow a choice, but they cannot establish how either Ranger will sit on a particular wrist. Wrist shape, proportions, and personal preference affect perceived size and comfort; the cited official materials do not provide comparative wear observations.

TUDOR says the Oyster Prince Ranger was introduced in the 1960s, first appeared in its catalogue in 1969, and remained there until 1988. The brand’s history page dates the pictured reference 7995/0 to 1967 and describes a 34 mm waterproof steel case with a matte black dial and luminous Arabic numerals at 3, 6, 9 and 12. That history provides context for the name, but it does not by itself demonstrate uninterrupted design continuity with the current collection. See TUDOR’s history of its 1960–1969 origins.
