I have the Certina DS Action Diver Titanuim. The clasp is fitted with a ratchet diver extension. The extension I feel is very loose. If the watch lays just sligtly down to my hand, it easily extends the extension the whole way open without much force if I flex my hand. I.e. it happens all the time which is quite annoying indeed.
Anyone who owns a Certina with this type of clasp, or have a similar clasp? What are your experiences, does the extension stay or is it loose for you as well?
I have sent the watch to Certina, but they returned without doing anything to it. The watch is a couple of months old.
Show the inside might help more. My guess is that the ratchet teeth are gunked up. This happens with ratchet wrenches, bicycle shifters. Crud clogs the normally sharp detents.
The ratchet teeth are quite clean. I can see some wear on the teeth, can it be so that titanium is not a very good material for this type of ratchet as it deforms quite easily?
I’ve got the same watch, but haven’t had any issues with mine (no yet anyway). Wherever I set the extension is where it stays.
I can close it without too much pressure, but it won’t extend without holding both buttons down. Here’s a pic of mine for comparison.
If it’s not holding in place I would send it back again. You’re still under warranty so I’d ask them to replace it.
Actually been thinking of swapping mine over to a NATO instead.
Thanks for the input, will ask for a replacement clasp 👍
