The brand new thick black military leather strap in the pictures. Lightweight, comfortable and comfortable with allot of cool features. The board looks early as its a ceramic board with plastic housing. It is also quite a large watch from this era as most are a lot smaller. These are notoriously difficult to fix as they are on a ceramic board which is susceptible to damage from acid or wrong battery being installed and cracking the board. Battery installed and nothing!

Tutto ok, perfetto per me You can find many varieties of Jump Hour from so many brands many of which have now gone. Well worth the wait. I have done nothing to this watch and its in the condition I bought it. I stripped the plastic surround off cleaned the board with IPA alcohol with a fibre pen. These are the types of watches I wore at school.

Love the Watch and I will be hopefully dealing with this guy and Catawiki again. This really as one of the nicest digital watches I have. Once arrived and examined I soon realised that the Sorna was missing a wheel that drove the autowind mechanism to wind the spring.

The end result was pleasing and would be perfect if I can ever find a donor crystal. Removed the rubber contact strips on the LCD and gave them a good clean.

This watcch now not running. Once your payment has been processed, you will immediately be able to place your bids again as normal. I had to relume the dots on the dial to complete the look. In all it took 3 donors to finally get it to work. Absolutely fascinating considering these were made extremely cheap and caused the quartz crisis in Switzerland yet they have lasted some 30 odd years and still work providing there is no battery leakage.

I left the battery in all night and in the morning to my surprise it had fired up!!


After this I refinished all the caserepolished all the bright parts and applied a brushed finish to the flats. Fedex was a little disturbed but all is correct, now. Case is completely bonkers shape and the odd times I do wear it I get some rather funny looks.

How kind Thank you Max. If you have one or know anything about LOV brand please get in touch.

I spent weeks trying to get the module to work including changing the oscillator but my electronic skills a poor and I could not get to work. Create a free account. Congratulations on winning this lot. Time is shown digitally on its display, I have to say though when wearing that it is quite hard to read.

Thank you for bidding on Catawiki! This is a very nice watch! This is a great solid and chunky stainless steel watch, very well constructed and again with a thick and well engineered bracelet. supsrnova

Valid bid!

I made a full video of the work on this watch which you can find here. When I opened the caseback I was met with a corroded module and two batteries probably dating from the 70s. Beautiful dial and shape, so unusual and that is why Byler like it so much. This then became a challenge to get one working. I did my now infamous trick of keeping it in my pocket.

I spend hour on this thing. You haven’t verified your email address yet. Extensive battery acid damage had done its worst and ruined the module. This really is just one for the collection rather than everyday wear.

The entire staff was working under the wach I know very little about this unusual jump hour watch. If you win more than one lot sold by the same seller in the same auction, your shipment will be combined.

The watch is powered by a manual wind movement and keeps very good time. A non runner it came to me in good condition and in its original box! Supernoba joblot find and also with a broken screen however I knew I sypernova a buer from a watch I was given a while before.


I had to source a new stem and the bu,er way to do that was to examine the mechanical part of the watch for a makers mark. Indeed, at the advent of quartz watches, which replaced the mechanical watches, Buler started to build up their image as a streamlined brand in the middle and upper watcch range.

I think this phase in the 80s was interesting, holding onto the analog watch but integrating all the good features of a bulfr, this one has stopwatch, alarm, dual time.

The watch will be sent as very-well packaged with registered post and tracking code after auction ended.
