  1. Hello! The story so far: I take on a friend's watch. It was his Grandad's and obviously has a lot of sentimental value to him. The case has lost almost all of its plating, there's some dial damage and the glass is all cracked. The dial indicates it's a Nivada, looks like it's from the 50's to me. Anyway, I agree to replace the glass and look it over for him and I thought it would be nice to service it, so disassemble and put it into my faithful L&R (which is probably about the same age as the watch!) I normally put the base plate in a separate tray (balance cock attached) and this time is no exception. However, what I don't bank on is the fact that the lid from the mainspring barrel which was in the section next to it, travels across the separation grid, wedges itself between the balance wheel and the cock, then takes out the balance staff pivot on the plate side......aarrgh! Hmm. So, new balance staff required. However I can't identify the movement. Some photos are attached; does anyone recognise what it is? At least if I have an ID I can start the process of getting hold of a staff to fit! Thanks for your help! Andy
  2. Morning guys (at least in South East Asia!) Digging thru my collection to find something to wear this Friday I pulled out this. A 'Croton Nivada Grenchen Aquamatic'.. now that's a mouthful, as the actress told the bishop. Inside we find a nicely finished ETA1256 movement. This would be one of the first ETA automatics. ETA kindly provided instructions on the rotor (hammer)... "TO REMOVE HAMMER ASSEMBLY UNSCREW 3 SCREWS 'A' ". Probably they were worried that watchmaker of the day would have problems with these newfangled technology!. Croton were one of the early innovators of waterproofing and they achieved this on early models with a case back that was fastened by 4 screws. These might have worked back in the day but they're just a pain today as the screws are usually badly damaged. This example is a bit recent and has a screw down case back. I wonder is the stamped 61S denotes year of manufacture? Groton watches are not too rare but stainless steel cases are less common and you usually find basemetal cases watches. I've got it on a vintage brand which is super supple and suits the watch. It is similar to a 'bonklip' in function. This is the bandmakers mark. Cheers! Anilv
