Hi I have a Victorinox Maverick Chrono model # 241432 which uses an eta caliber 251.272 movement. 

Today after changing the battery I noticed that it was still struggling to run properly. Any small bump would cause the seconds hand (in the lower 6 o'clock chrono) to stop and a gentle tap from the side or pressure to the back would get it running again momentarily. The chronograph aspect of the watch still runs just fine if I activate it so I am confused as to what could be going on with the seconds hand. I took it apart to check for debris and the seconds hand still moves freely, but will not run. Any ideas? 

Worst case I am looking at ordering a replacement movement - but am also wondering if the date wheels are swappable. The replacement movements I have seen have the dates oriented for a 3 o'clock date window, whereas; the Maverick has the date window at 6 o'clock. 

Any info/tips would be greatly appreciated!

sooner or later Any timepiece that has gears including quartz watch needs to be serviced. In other words taken apart cleaned and re-lubricated. But typically on quartz watches most of the time you can find a replacement movement. Otherwise you would have to service the watch.

I think it's just the printing on the disc for the date so if you change the disk I think it will work out fine. Providing there on even hours I think there is somewhere they could be like in between an hour and then that will not swap to another one because then you'd have half-and-half in the window.

Hi  Typically the chrono's have three registers one for each discipline, so whilst the other two are working ok the third is struggling. As John said quartz watches still need a service. The mechanical assembly still needs to be clean and lubricated.  The attached documents will enlighten you as to what is required.  The movements are listed as discontinued on Cousins web site. there were three options regarding the date.  date at 4  on two and date at 6 on the third.    Searching for a donor may be an option unless new NOS can be forund.  speedtimerkollection.com  or welwynwatchparts.co.uk are retailers of second user bits and movements.        cheers

      Hi to Blackminou29–am a collector/ caretaker—good luck to you following your repair course—with hindsight I wish I’d pursued a career in both watchmaker/ jeweler fields—good luck with whatever career passion you engage.   Thank you Watchweasol for posting the amazing TZIllustratedGlossary!

      Seiko 6601 Tech Sheet?

      By JohnR725 · Posted

      yes I noticed the new site and I miss the old site. It's the unfortunate problem of the Internet here today gone tomorrow sometimes some of the stuff gets backed up and sometimes well it does not then the problem with the early Seiko's were there were not necessarily designed for distribution across the planet and as such there is no customer support for them. So trying to find early stuff like technical information or sometimes even parts list for older Seiko is is problematic. But I did find you a you tube video. A quick look he seems to take a heck of a lot of time to actually get to the service single I did not watch all that but it does look like he did disassemble or started to say there's a tiny bit here

      An intro…

      RichardHarris123: Hello and welcome from Leeds, England.  I have family all over Australia, went as £10 poms Thanks Richard. Hope you’re able to visit your family here and that they’ve all done well 🙂 My relatives arrived from England in the 1790s transported on the ‘Second & Third Fleets’—a story of timber sailing ships, of convicts and doing well in this huge Country of Australia. When I visited the UK in the 1980s, I was too young to comprehend the depth and breadth of its history…  Best wishes, Mike William Chapman, my 4th great Grandad’s charges, at age 23 read at the Old Bailey; sentenced to 7 years of transportation to Sydney.

      New balance staff not riveting to balance

      By Endeavor · Posted

      The whole process and the progress are closely observed, it's hand-driven and very controlled. I can't see the "danger", unless you are watching the TV while doing it. As you could have read, and in this quote "wheel" is the balance-wheel.

      AS2063 - hand setting

      By Mercurial · Posted

      Have you got the pallet fork installed in the movement when you see the train move when using the setting works? As nevenbekriev said, without the pallet fork to lock the train, the behaviour you are describing is normal. If this is happening with the pallet fork installed, you have a problem in the gear train, it should be immobile when the pallet fork is locking the escape wheel.  The fit of the circlip above the pinions on that wheel is crooked in your pictures, it should sit flat up against the upper pinion as in Marc’s picture.  Hope that helps, Mark
