Bertucci field watch crown release


Recommended Posts

Hi,

I need to replace the hands on my bertucci field watch and can't seem to locate the crown release. I was wondering if anyone Has experience of these before I start prodding bits!

I've attached a photo of the inside below.

Thanks for any help you can give.

Your watch uses the most popular Miyota quartz module. The stem release point is the small round point, left to the round setting lever post, which is left of the stem itself, near to the bottom.

Thanks @jdm. It was slightly stressful doing this for the first time. I wouldn't have wanted to do it on a watch more expensive than this! 

Found the little dimple - you need to apply a reasonable amount of pressure and the crown popped out. For anyone who is interested, you can see the release here:

The second hand presses back on easily, and pops into place. This one dropped off when I dropped the watch face down on a hard floor. These watches have a deep bevel and tough glass, so no other damage.

Quite enjoyable to be able to fix it, and saved me another 15 quid to have it done. I used a rubber ball to remove the screw back and some fine tweezers to press the mechanism, so it didn't cost anything.

Job well done.  I have much respect for the Miyota movements as well.  Two of the watches my daughters wear have Miyota modules in them.  And though I try to instill in them a respect for timepieces, my daughters are not gentle.  They are very active out-of-doors.  Their watches often lead a hard life.  The cases are thick and stout, but they get knocked about quite a bit.  Yet they've never needed anything but a battery change, light cleaning, very little oil, the usual stuff.  Robust little quartz things, those Miyotas are.

I do happen to replace failed Miyota modules at times, two in the last weeks. I don't investigate about the cause or exact failure, at €5 each it's really no big deal.

    • The Boro has changed quite a lot over the last 20 years, and not for the better. I actually moved out of the town 15 years ago to a small village not far away. Thanks for the pdf! Looks a great read. I'll get it printed today and put it on my work bench!
    • Not having all the fancy equipment, this is a way I came up with. I never said it was the best, the most ideal or the safest way. Working on balances is always a delicate task and full concentration & common sense should prevail. I was well aware of the "dangers" / short comings involved, hence my "warnings", as quoted above. The balance wheel of the Omega was nice true, flat and one could clearly see how much gap there was left before the grinding wheel would touch the balance wheel. My idea of penning this article was to show/share a way which, in my case, perfectly succeeded. If deemed to risky, or if the balance wheel is not true or has a wobble, other methods have to be followed.
    • I loved his explanation of a teardown 😅 Ex military Richard Perrett, pretty knowledgeable guy.
    • I also see a bit of danger for the wheel, at least you have to keep away from it and may get a too thick rest ring. My rest rings are about 0.05 mm. Better way would be a grinding wheel touching the staff with its circumference. Frank
    • Not easy to find this one everywhere,  so it depends where you are located. Joining it back together might be possible, i have silver soldered mild steel before even with traditional plumbers lead and its a pretty strong joint, but bere in mind this is only 1mm diameter.  The join would need to be very accurate,  it not something i have heard of anyone trying before. The part no 401 is the swiss code number and relates to watch winding stems in general
