Damasko DA36 Repair (2019)

Created Monday 18 November 2019

15/11/19

Sent an email asking for advice on having the watch repaired on 15/11/19 :

Good morning,

I bought a DA36 in October 2016, direct from Damasko and I have been very pleased with it and it has been very reliable, keeping good time over the last 3 years.

The serial number is DA36.1981

Recently I have noticed that it randomly loses a up to one minute in a single day, when most of the time it keeps to within ± 2 seconds per day.

On these occasions I have observed the watch using a Timegrapher machine, and I see that the displayed rate can be as low as -240 s/d and the displayed amplitude can be as low as 126 degrees. These periods of poor performance occur randomly and do not appear to be related to any physical activity etc. Often the watch returns to normal behaviour after a few hours. I now feel that I cannot rely on the watch to be reliable in normal use.

Can I arrange for the watch to be repaired or serviced to return it to it's previous excellent and reliable performance?

Since I bought the watch direct from Damasko I am happy to return it to yourselves for the repair.

Please advise me on how to proceed.

Best wishes,

John Pumford-Green

I would send you the invoice for payment by PayPal when I get the watch back by our watchmaker. May I know which invoice and delivery address I can use?

Now to wait for the repair to be complete.

What is “many abrasion” in the escapement - did I do it while regulating - introducing some foreign bodies, dirt/dust? Will not do any further regulation once I get it back, and just have it serviced every few years…. I can put up with a few seconds/day here and there, as long as it's not > ± 10s/d

Damasko DA36 Tests 1 (2019)

Created Thursday 31 October 2019

Investigation into fault last seen Aug 2018

Fault symptoms from 30/8/18

rate error high (> 30s/d) and dependant on position
amplitude low ≤200°
hand-winding would not increase amplitude or improve random fluctuating rate.

Investigation to confirm fault prior to arranging repair : 30/10/19

wind 40 turns manually & set time: Δ = -0.7s
on wrist 19:00
take TG measurements as auto power builds up over evening

Conclusion

There seems to be nothing wrong.

4 full days of on-wrist testing shows normal amplitude and rate error.

Power-run-down test gives a reserve time of ≥33 hours. This is less than the ETA 2836-2 spec of 38 hours. This may be due to starting the test with less than full wind? 33 hours is still acceptable. Rate and amplitude drops after 24 hours, but accumulated error is still acceptable if the test had been stopped before completion and the watch worn (an additional ~5 seconds of loss over the 33 hours of testing).

Restarting and achieving full-power/amplitude & normal rate error takes some time on-wrist - avoiding manually winding as far as possible, just enough to start the movement running. Is there still an intermittent problem with the winding or power?

Time will tell.

Repair and Service 2022

A mishap leading to having it repaired and a full service at Damasko

The Accident 9/11/22

I dropped my watch!

I dropped it face down, “flat on the crystal” on a tiled floor! I was initially relieved to see, when I picked it up from its landing place, that the crystal had survived. I initially thought I'd been lucky, and it had escaped unscathed.

However the shock of landing had dislodged the layer of luminous paint from the minute-hand. It came off in one single piece, and was free inside the watch, looking like another hand just rattling around inside.

The watch was now 6 years old and was probably due a service, the timekeeping had slowly drifted to around -2 seconds per day and appeared to be getting gradually worse month by month.

I emailed Isabella at Damasko to ask about the possibility of a service and the any repairs necessary, including a new hour-hand. She replied very quickly to say that a Full Service would be €260 and new hands were €25 each. The hand replacement would be done as part of the service (no additional costs beyond the part(s) themselves.

Sending it to Barbing 9/11/22

We aren't in the EU any more. What idiots thought that BREXIT was a good idea??

In the past it was simple, and quick, to send something back to Germany for repair. Not this time.

I used Royal Mail, but this time needed to declare the contents on a Customs form, and hope that the German Customs assessor didn't apply import duty on the way IN to Damasko (and then hope that the UK Customs don't charge me on the way back).

The watch was posted on November 9th 2022 and arrived, after a long delay in German Customs, on December 1st 2022.

Repair go-ahead 5/12/22

I received a full estimate, including return carriage of €100 (Brexit again!), of €385 on 5th December, after the watch had been examined by the Damasko watchmaker. This was for full strip-down, clean, inspect, lubricate, rebuild, test/regulate, water-proof check etc. as well as replacement of the hour-hand. I gave the go-ahead by return email.

Invoice received 19/12/22

The repair was done, some additional parts were needed (second wheel, intermediate wheel and third wheel).

The invoice was received and I arranged payment via PayPal the next morning.

The watch is on its way back via FedEx, on 20th December. Now I have to wait to see what happens on the return trip. What will UK Customs do? How long will it take.

And how will it run?

— John Pumford-Green 22/12/22 06:58

Watch returns... 30/12/22

Against all expectation my DA36 came back before the end of the year. It was delivered on Friday 30th December.

It came in a nice parcel with a Damasko Baseball Cap, Damasko pen, catalogue, Christmas Card and the old parts that were replaced in the service.

It's such a pleasure to have my watch back on my wrist again after over 2 months.

I'll keep track of its timekeeping now. Before the accident it was gradually slowing, and had reached the point of losing 4 seconds/day. It will be interesting to see what the rate is now, following a full service, in which 3 train wheels were replaced. I'll put it on the Timegrapher tomorrow afternoon once it's had 24 hours of normal wear to get fully wound. I'll also start a new “WatchCheck” measurement period to observe the overall daily rate each morning, as usual.

The DA36

I see this watch as a modern version of Rolex's Milgauss - tough with the same level of Magnetic Resistance as the original Milgauss (1000 Gauss). The original anti-magnetic engineer's watch from Rolex wasn't the multi-thousands-of-pounds bauble they sell today.

Originally Rolex produced relatively expensive, but still affordable, tool-watches.

Unlike the Veblen Goods they churn out today.

Damasko's original and iconic watch, the DA36, is something akin to an early Rolex. Not cheap, but also not ridiculously over-priced. It has no obvious external frills, but has plenty of technology inside to justify the price and to add functional value.

I often ponder whether I'd buy a Milgauss if I could afford the £7000+ price tag. And now I've lived with the DA36 for almost 6 years I don't know that I would. My watch is now my watch. Why swap for another expensive toy?

Damasko have recently re-configured their range of watches and dropped the DA36, and most of the others from their early years of production, as they move upwards, into making higher price watches with in-house movements, rather than using off-the-shelf ETA units.

I'd love a DA36 to appear with the in-house movement, but I don't know that this is going to happen.

UPDATE — John Pumford-Green 24/04/23 17:45

The DA36 has now reappeared - as the DK36 with the new in-house A26-3 movement.

DK36 at Damasko

My watch developed a fault after a couple of years but this was easily repaired by Damasko. I might have introduced the fault myself after opening it up a few times to regulate it - perhaps I let in some dirt that found its way to the escapement and caused some abrasion?

I don't know.

It's now working perfectly well after 2½ years of continuous daily wear. I only take it off to have a bath/shower and (usually) to sleep, and very rarely if I need to squeeze my left hand into a tight space when working on cars, Land Rovers or transmitters. I don't think I've let it run down since the repair in December 2019.

The Milgauss

A modern Milgauss for comparison. There's not a lot of aesthetic similarity, the modern Milgauss is quite gaudy, with its green sapphire crystal and shiny dial.

The 1960's version ref. 1019 (not the original submariner style with a timing bezel) looks more workmanlike and is the one I'd go for if I had the money. When I last looked a birth year 1966 Milgauss fetches around £22,000…. so I'll stick with my DA36 and let it age with me.

The Damasko Steel Bracelet

The DA36 was bought with the Damasko steel bracelet and initially I was happy with it.

It is super-engineered. Each link, of ice hardened bead-blasted steel to match the watch's case, is fixed with strong torx secured pivot pins. The whole bracelet can be dismantled for cleaning. It's very strong, very well designed and very well made.

After time though the lack of adjustment (even with the two supplied “long” links) meant it became difficult to find a good comfortable fit.

The DA36 was then worn mostly on the Damasko leather strap or a variety of NATO straps, including some elastic MN types, which are certainly very comfortable.

The steel bracelet was sold in 2017, to someone in the USA, after I decided I couldn't get on with it.

Following the appearance of the rate-error fault in 2018, I switched to my Seiko SKX007 on a Strapcode Oyster steel bracelet, and liked it so much I decided to buy another Damasko steel bracelet for the DA36, and to request a set of additional adjustment links to allow more variation in size. The longer links can be bought in sets of 2 pairs, which along with the 2 pairs that come with the bracelet, allow a smooth adjustment in tiny steps, almost matching the difference made by adding or removing a normal link.

The new bracelet and links were bought in November 2019.

This allowed the use of up to 5 ¹⁾ adjustment links to step smoothly between the jump in one normal link. A good fit was obtained with 3 or 4 added long links. After some time I found I could wear the bracelet with no adjustment links, my wrist settled to a size that suited a whole number of normal links, but I have the option of a good range of adjustment, if things should change in future.

I occasionally put a NATO strap on, but it rarely stays for more than a day or two before the pull of the super-strong super-engineered bracelet wins out.

Update May 2022

I've owned the DA36 now for over 5 years. After the repair, and getting the 2^nd bracelet, it's rarely off my wrist. I'll occasionally wear another watch (typically a Casio GW-M5610) on my right wrist.

The DA36 stays on the left.

The ice-hardened steel is very resistant to scratching or other marks. After 5 years I can see some slight blemishes - just signs of an active life. The bracelet has more marks than the watch case itself - links rub against each other and the bracelet is more likely to be rubbed against hard surfaces than the watch - and as time goes by it slowly (very slowly) starts to look less like a new watch and more like a tool watch.

There are marks on the bezel, and on the bracelet end-link, at the 12 o'clock position, I guess I caught it on something abrasive at some time…. more wabi-sabi

The hardened steel, and matte bead-blasted finish, mean that there is no slow development of a general swirly patina. A scratch shows up, in the right light, as a shiny area of un-bead-blasted reflective steel. It's just the characteristic of the material. I wonder what it'll look like in another 10 years?

Time Keeping performance

Still well within COSC standards ( -4 / +6 ) at around -2s/d as of May 2022. Rolex now guarantee their watches to run better than COSC, at ±2 s/d. My DA36 has been within this range for the last few years, and is only now starting to fall outside that range. It may wander back towards zero over time. Who knows how all the different variables inter-react to make up the overall rate error, and how they vary with time?
