Strap for Datejust 31 Yellow Gold / Fluted / Silver - Roman / President

The Rolex Datejust 31 reference 278278-0028 features a 31mm case with a lug width of 16mm. This measurement should be taken with a calliper between the two lower lugs of the case to ensure a precise fit for any replacement strap.

For a Yellow Gold case such as that of the Datejust 31 278278-0028, the most suitable materials are alligator leather in cognac or tobacco tones, vegetable-tanned calf leather, and shell cordovan in bordeaux. These materials complement the warmth of yellow gold and develop an authentic patina over time.

To replace the strap on the Datejust 31, a spring bar tool suited to Rolex lugs is required — ideally with a fine tip and a safety fork. The 16mm spring bars must be removed carefully to avoid scratching the gold lugs. It is advisable to work on a soft surface and to verify the spring bar diameter before purchasing a replacement strap.

The lifespan of a leather strap depends on the material, care, and frequency of wear. A quality vegetable-tanned calf leather strap typically lasts 2–3 years with regular use; alligator or shell cordovan can exceed 5 years when treated with appropriate conditioners and stored correctly. Prolonged exposure to water and perspiration remains the primary cause of deterioration.
