Original specifications
Sizes and specifications apply to the version named below. Other versions can differ.
Original Benrus Type I, MIL-W-50717
Original issued Type I is a historical candidate; current reissues are distinct variants. Exact original reference/configuration varies by production.
| Specification | Value | Sources and notes |
|---|---|---|
| Case width | 43 mm | Benrus Type I and Type II MIL-W-50717 Military Dive Watches | Worn & Wound One cited source. Source version Original Benrus Type I, MIL-W-50717. Worn & Wound search excerpt reports the original case at nearly 43 mm; treat as approximate. Sources differWorn & Wound reports 43 mm for the Type I/II family; the specific circa-1978 specimen listing reports 42 mm excluding crown and 44 mm including crown. Keep both until the convention/specimen scope is resolved. |
| Lug to lug | 47 mm | Vintage 1978 Benrus Type I listing | Rolex Forums One cited source. Source version Original Benrus Type I, MIL-W-50717. Specific 1978 specimen listing reports 47 mm lug-to-lug. |
| Thickness | 16 mm | Vintage 1978 Benrus Type I listing | Rolex Forums One cited source. Source version Original Benrus Type I, MIL-W-50717. Specific 1978 specimen listing reports 16 mm thickness. |
| Lug width | 20 mm | Vintage 1978 Benrus Type I listing | Rolex Forums One cited source. Source version Original Benrus Type I, MIL-W-50717. Specific 1978 specimen listing reports 20 mm lug size; Worn & Wound confirms fixed bars, so this is strap spacing rather than a spring-bar width. |
| Water resistance | 300 m | Benrus Type I and Type II MIL-W-50717 Military Dive Watches | Worn & Wound One cited source. Source version Original Benrus Type I, MIL-W-50717. The cited historic article associates the original Type I design with 300 m rating. |
Sources and unconfirmed details
- Case width conflict remains open: 43 mm family-level review claim vs 42 mm excluding crown on a dated specimen. Fixed bars: 20 mm is a strap width, not spring-bar lug width.
