1960’s BWC Buttes Watch Co. [Swiss] Sport-Diving Watch – ASST Cal. 96-4 With Date


Out of stock

A wonderful example of a BWC [Buttes Watch Co.] sport-diving watch that has been professionally inspected in-house by Localtime.

The case has not been polished, houses a manual-wind ASST Cal. 96-4 with date at 6h and measures in at 38mm at the bezel and 41mm including the crown at 3h. The stunning sunburst blue Tritium dial, bi-directional bezel, original plexi and hands are stunning. It is wearing one of my own Localtime ‘waffle’ rubber straps in blue that in my humble opinion, compliments the watch quite nicely. I have included many photos, including some closeup snapshots I took just for fun, to allow you to enjoy the lovely details of this fine timepiece.

As with all the watches that are handled by Localtime, the BIN price includes a written 6-month written warrantee from the date of purchase. Feel free to contact me for whatever questions you might have.

EXTRA! Check out the Localtime ‘waffle’ rubber straps: They come in 4 sizes [16-18-20-22mm], 6 colours of rubber [black, blue, brown, orange, red and yellow] and 6 different colours of stitching [white, grey, blue, orange, yellow and red]. The straps themselves have a ‘waffle’ pattern on top and a ‘grooved’ pattern on the bottom. Their length is 97mm on the buckle end [including the steel buckle] and 118mm on the tail end; so not short but not too long either. They have two floating keepers with the same rubber ‘waffle’ pattern. A good quality pair of spring bars is included with each strap. You can see them in the last photo here and they can be purchased separately from my eBay store under eBay item number 202061460884.
