I’m not sure where my pictures went. I guess I’ll repost. I sincerely apologize for the double post. I cannot figure out how to edit my previous post or why my pictures aren’t showing up.

Seiko 5 Sports SpeedTimer Flyback Chronograph:

Today I'd like to present a Timex 202, all original. This is a very rare piece.

The module had several damaged wire bonds, but I only took a few pictures. The second picture shows the damaged wire bond on the lower colon before repair. Fixing wire bonds that are broken off of semiconductors takes silver paste and a brain surgeons steady hand. 😄

Another Timex. I believe this one dates to the early 70s based on the EB 8461-73 one jewel movement. Strange, this one. The one jewel is the roller.

I don't wear finger cots or use movement holders when disassembling cheap pin levers...only on reassembly. Fire away 😄

Purchased as never worn, new old stock, the first photo shows how it looked when it came to me. Unfortunately, the lower balance staff pivot was broken and the cost of a new balance and/or staff was more than the watch. After sitting idle for 2 months, I found a Sicura watch with a 17 jewel EB 8461 movement for $10. I swapped the jump hour parts over and now my wife has the only 17 jewel Timex jump hour (maybe). 😉

The first photo in the next post is how it looks now. It is beautiful and runs silky smooth!

I’m still waiting on the parts movement to fix the Lucerne chronograph above, so I did another of these last night (the one on the left). I’m starting to worry a bit. It’s been two weeks since it landed in Chicago (maybe it’s Chicago’s mail?).


Fully serviced, new crystal, the works...

Another eight hour marathon 😄

The Lucerne chronograph is off the table for now. The parts movement is no good.

Latest Timex model 87 (1970, West Germany Electronic Durowe cal. 882). I’ve discovered two significant modes of failure on these:

The first is a weak arresting magnet for the index wheel (understandable as they are 50 years old). This allows the index wheel (I call it the ninja star...it will disappear like a ninja, too) to backtrack too far when the index lever (like a pallet fork) retracts. Essentially, the movement ticks like its running, but the second hand won’t move because the index wheel is not actually advancing. 

The second is a weak capacitor in the control circuit. Again, 50 years old, so not surprising. The 220-250nf capacitor holds a small charge generated by the balance coil during its initial stroke, releasing that charge on the backstroke to drive the balance. A weak capacitor results in low amplitude, again causing the watch to tick, but not advance the index wheel or second hand. Replacing the capacitor solves this issue.

I've been busy...rebuilt 25 or so Timex Electric and Electronic watches in the last month or two. 32 more in the que. I heard there's some guy around here that likes to shoot the movement with contact cleaner and call it good. That's a shame. I can fully rebuild one of these, including wet sanding and polishing the crystal, in about 3 hours. No need for cutting corners 😉

I am the Timex whisperer 🙂

Some...

A fair handfull, nice to see the TIMEX is well represented and not treated with scorn, they were in their time innovative and ahead of their time well worth keeping the name alive.

I absolutely love the Electric and Electronic models. Easy to work on, great runners and gorgeous.

Some more that I've posted around the forums (personal collection):

      Questions about my Bravingtons Renown Mantel Clock

      By rjenkinsgb · Posted

      Off topic, but that just brought back an old memory! My mother once told me about a minor incident as a child (born 1917, so 1920s, at a guess). She used to use "Fish glue" for a hobby - an apparently smelly glue that had to be heated to be usable - and to heat it gently, she had to stand the tin in the kettle.   One day someone filled the kettle without seeing the glue tin.. The tea tasted of fish for some time afterwards!

      Balance cock stud screw

      By Neverenoughwatches · Posted

      As Richard said, this is a really old school trick for joinery.  Cut i strip of paper, might need to be watch paper  around 1 " x 1/2" lay it over a staking block then press the stud screw into and through the edge of the paper upto the head of the screw. You probably wont even need to pull the paper away the head will pull itself through.

      Waltham 6/0 d winding stem

      By ooteenie · Posted

      Hello,  i am looking to source a winding stem (winding arbor) for a waltham 6/0 d movement. I have found some that claim to fit 6/0, 6/0s, 6/0b etc and somealso claim they will also fit the d as well. The d does have hacking which is driven by the stem seating completely. Given some of the costs of these, i was hoping someone would know of any interchangeability with a source, or know a source where a confirmed 6/0 d stem can be had. I am in the US so a US dealer is best.    thanks in advance.

      So great to see and hear- your mum looks great! …my mil had a stroke last summer in the golf course parking lot. I’m flying out tomorrow to visit and play golf. she’s ornery because she can’t get off the tee but I hear she makes up for it on the greens since she’s been putting since a week after her stroke 🧐…
