===== 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 [[wp>veblen_good|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 [[https://en.wikipedia.org/wiki/Manufacture_d%27horlogerie| 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.

[[https://www.damasko-watches.com/en/DK36/SW10053.10 | 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 =====

<WRAP group>
<WRAP half column>

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.

<WRAP half column>

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 [[https://www.damasko-watches.com/en/accessories/manufactory-steel-bracelets/158/manufactory-steel-bracelet-ice-hardened-stainless-steel|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 [[..:inventory: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 ((yes, I've actually got 5 pairs in total, can't remember the details of how this happened!)) //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<sup>nd</sup> bracelet, it's rarely off my wrist. I'll occasionally wear another watch (typically a [[..:inventory:casio_gm-w5610|]]) 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 [[wp>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?
