Veau Jonathan Calf - Hermès Leather for Watch Straps

Absolutely yes. The rigidity of Veau Jonathan is perfect for supporting a Datejust 36 without giving way. The aesthetics are also fitting: the natural patina that develops over time pairs beautifully with vintage cases and yellow gold or steel bezels. I recommend starting with a 20mm size if your lug width is standard. The only caveat: keep it dry.

The signature of Veau Jonathan is its compact grain, almost invisible at first glance but tangible to the touch. The coloration is typically a warm natural brown, without excessive staining. When held, you'll sense important density and a structure that isn't waxed but naturally oiled. Furthermore, Hermès never applies glossy finishes to their Veau Jonathan: the finish is always satin. Another detail: the leather has an unmistakable scent of vegetable tanning, slightly astringent. If the leather feels too plastic-like or smells synthetic, it's not authentic Hermès.

It's a conscious and fascinating choice. Veau Jonathan holds well the 22mm required by a Seamaster 300M, and the patina it develops over time adds character to an already robust watch. The compatibility lies in the fact that the leather doesn't fear salt water as much as other leathers, thanks to vegetable tanning that makes it naturally oily. However: for a sports watch like the Seamaster, an alligator or rubber-leather might be more appropriate, less porous. But if you love casualness and vintage, Veau Jonathan is brilliant—precisely because it contrasts the technical character of the watch.
