Following up on a thread started by Willith a couple of years ago regarding bronze buckles for the bronze cased watches, I contacted Simona of Di Stefano Straps, located appropriately enough in Firenze, Italy.
Though the web site, in terms of watches, is primarily focused on servicing Panerai needs, there are bronze buckles available there--though only 24mm and 26mm are listed. I inquired about 22mm, learned that they could be made special order, so I went ahead and ordered three buckles, one in each size: 26mm for my 26/26 Toshi custom-made strap on my Bronze Nautilo; 24mm for my 24/24 strap made by forum member "igory76" for my Bronze (orange) Polluce, and; 22mm for my 22/22 Gunny strap, again custom-made, but based on his "Breitling Aviator" strap, for my Bronze (black) Polluce. The Gunny strap has very appealing brass rivets, rather than the usual steel, so this too matches well with the bronze case.
The bronze Simona uses appears to be pure, so the color is much redder, and brighter, than the bronze alloy formula that Anonimo uses for their cases, so the match isn't perfect, but it is nice. One nice feature for all three buckles is that they use a double screw assembly for attaching to the watch strap, much like the screws Anonimo uses instead of spring pins for attaching straps to the lugs--these screw assemblies also appear to be bronze. A few other points should be made--all three buckles are the "Pre-V" style, and are big! At the widest point of the mid-sized buckle (24mm), for example, the width is 38mm! A second point is that the underside edges, which contact the skin, are fairly sharp upon arrival, so I had to file all three of them down a bit to keep them from irritating the wrist. Further, the buckles appear to be coated with some sort of protective seal in order for them to retain their brightness forever. This may not be appreciated for those who like "patina" (I don't, as I grew up crewing for racing yachts in the San Francisco Bay (salt water), and the last thing anyone wanted on their brass, bronze and steel cleats, housings, pulleys, etc., was "patina"--i.e., left unattended, this becomes rust, corrosion and eventually destroys the metals.) I have heard that another owner of one of the Simona bronze buckles has worn his so much that the coating is gone, and it is now aging "properly"--if so, I suppose someone could lightly sand the buckles off to give them a head start. Finally, please note that the three sizes available will not work on most of your Kodiaks (for those watches with the 42mm cases) as Kodiaks taper from 22mm to 20mm at the buckle. I don't like tapered straps, and I don't like mass-produced straps, even Kodiaks, so this wasn't a problem for me. (And, if any of you are trying to figure out what is wrong with my wrist or arm--I am left handed, so the watches are on my right hand. Also, for comparisons, my wrist is 7 1/8 inch.)
Obviously watches, straps, buckles and so forth are all very subjective--below are the combinations that work for me, and hopefully they will be helpful in giving you an idea of what may or may not look good on your own watch(es). Enjoy!
