Strap for Rolex Oyster Perpetual 34 6634 Golden Egg

The Rolex Oyster Perpetual 34 ref. 6634, produced in the 1950s, features lugs with an internal width of 19 mm. This measurement is specific to this generation and differs from more recent Oyster Perpetual models, which use 20 mm lugs. Before purchasing a replacement strap, it is advisable to verify the lug width with a calliper between the lugs.

For a vintage timepiece such as the ref. 6634, a vegetable-tanned alligator strap is the most refined pairing: the natural scale texture and the patina that develops over time complement the understated 34 mm case. Alternatively, a padded calf leather strap in tobacco or black offers everyday durability. For more casual use, a nylon NATO strap is lightweight and practical. The correct width is 19 mm.

To replace the strap on a Rolex Oyster Perpetual 34 ref. 6634, use a spring bar tool to remove the spring bars holding the strap in place within the lugs. Insert the tool into the small notch on the side of the lug, compress the spring bar and slide the strap out. The process is straightforward but requires care to avoid scratching the case: it is recommended to protect the lug edges with masking tape before starting.

Yes, high-quality aftermarket straps compatible with the Rolex Oyster Perpetual 34 ref. 6634 are available, provided they feature a 19 mm lug width.
