The Goldilocks Datejust
The Datejust 31 (Ref. 278271 and variants) sits perfectly between the Lady-Datejust 28 (too small for many) and the Datejust 36 (too large for some). At 31mm, it’s the fastest-growing segment in the Datejust family — driven by women upgrading from 28mm and men with slender wrists (under 6″) who find 36mm overpowering.
Movement: Caliber 2236
The DJ31 uses the Cal. 2236 — a different movement from the 3235 in the 36mm and 41mm. Key differences:
- Syloxi hairspring: Silicon-based, produced by Rolex’s MEMS (micro-electro-mechanical systems) process. Paramagnetic, temperature-stable, 10x more shock-resistant than metal hairsprings.
- 55-hour power reserve: Less than the 3235’s 70 hours but adequate for weekend-proof ownership.
- Superlative Chronometer: Same -2/+2 sec/day accuracy standard as all modern Rolex movements.
Available Configurations
The DJ31 offers the WIDEST configuration range of any Datejust size:
- Materials: Steel, Rolesor (yellow, Everose, white), full gold (yellow, Everose, white)
- Bezels: Smooth, fluted (gold), diamond-set (gold)
- Bracelets: Oyster, Jubilee, President (on gold models only)
- Dials: 30+ options including MOP, diamond indices, sunburst colors, pave diamond
The sheer configurability makes the DJ31 the most customizable Rolex in the catalog — more options than any other reference.

Who Buys the DJ31
- Women (primary market): The DJ31 is the #1 women’s Rolex by sales volume — larger than the 28mm, more feminine than the 36mm
- Men with slim wrists (5-6″): Growing segment — men who find 36mm too large are discovering the DJ31 as their perfect Rolex
- Couples: Many couples buy matching DJ31s or a DJ31 + DJ36/41 as complementary his/hers pieces
Frequently Asked Questions
Is 31mm too small for a man?
On a wrist under 6″: no — 31mm is proportionally correct. On 6-6.5″: borderline — try it on. Over 6.5″: probably too small. Remember: 31mm was a common men’s watch size until the 1960s. It’s not “too small” — it’s vintage-proportioned.
DJ31 vs Lady-Datejust 28?
The DJ31 uses the newer Cal. 2236 (vs 2236 in the LD28 — same movement). The 3mm size difference is visible but not dramatic. The DJ31 wears slightly more “unisex”; the LD28 is more traditionally feminine. For versatility: DJ31.
