In the main scene of our exceptional Watch Strap Review arrangement, we’ll investigate the Doxa Expandro bracelets.

Vintage watches are great for such countless reasons. They either address a period in watchmaking history or maybe associate you to a friend or family member as a family legacy. Vintage watches may have a complication that is as yet intriguing and scant after numerous years. We have examined vintage watches at an extraordinary length on Fratello. From straightforward 3-handers to complicated watches, Fratello has covered loads and heaps of vintage watches from many brands. Try not to stress, we are proceeding to do that. All things considered, this is one of our forté. Despite the fact that we need to zero in on “other stuff” that comes with a watch. What’s more, what are those embellishments you get/need more often than not with a watch? Wristbands, obviously. In this revived Watch Strap Review arrangement, we will take a gander at a portion of the unbelievable wristbands we vintage gatherers’ chase to complete our valuable watch. Like the Doxa Expandro.

When it comes to extras my view on the inquiry is the accompanying; You can’t wear a crate, it enhances the watch to me. Except if we are looking at something truly uncommon and maybe additionally with papers. In the event that you gather something only for putting away it in the protected that is fine, however in case I’m searching for a vintage observe on the grounds that it comes with a crate yet maybe no papers, it’s anything but an or more – for me. This, in any case, isn’t the situation with wristbands. Certain watches can command an altogether more exorbitant cost if the first arm band and end joins are there. Simply think about a Rolex GMT 1675 with a unique bolted shellfish arm band. Omega a Pre-Moon Speedy with a 1039 wristband and 516 end joins. Ultimately, a vintage Doxa Sub 300(T) likewise arrives at 20-30% more if its unique globules of-rice or BoR Expandro is with the watch.

Beads of Rice

There are numerous vintage Doxa authorities and specialists out there and I’m not one of them. Accordingly I would prefer not to get excessively profound into the creation of these wristbands. My point is somewhat to bring these stunning, actually very much created arm bands to a more extensive crowd. Acquaint it with somebody who may have not seen or caught wind of them. Finally, to show how they work and what sharp little deceives they contained that made them a gigantic top choice among Doxa wearers and past. I’m certain a significant number of you have perused our article on the Doxa 300 SubT Sharkhunter. There is a part about the arm band in there that would give you an essential thought regarding them. However, we should see them somewhat closer. There are 3 distinct variants and 4 fasten varieties. The most punctual ones (like mine) had a fasten with “Doxa Sub 300” on them.


This is the one we will discuss. At the point when the most punctual Doxa Sub 300 turned out in 1967 it had this arm band on with a couple of coordinating end joins. Those connections have a reference number of 7720-4. Not long after the Sub 300, when Doxa delivered the second era of Sub 300 T’s a similar wristband accompanied the watch yet with another pair of end joins. It was the reference 7720-10 a somewhat unique variant of the 7720-4. The T meant the presence of Tritium on the dial, for example, the case with most vintage watches at that point. Gatherers regularly allude to these wristbands as “Expandro” because of the extending joins on the arm band anyway early forms were not set apart thusly. Mine just has a “Treated steel” stamp within the applauds. Expandro marked (made by a West German company, Kiefer-Cadman) wristbands came later.

How the growing connections work

Doxa Sub 300

I’m not saying that Expandro was not the maker on the early wristbands, in actuality. The framework Expandro marked arm bands utilized (as the company sold nonpartisan wristbands too under their own image name) was equivalent to Doxa’s. In this way, the association is there. Be that as it may, what precisely are those highlights? In the first place, dabs of rice arm bands are among the coolest glancing vintage wristbands out there. They are light yet solid, tasteful yet still rough enough to be added to a games watch. Notwithstanding, looks are scarcely the stunt here. On the two finishes of the fasten, you have a thick connection which can be seen as a plan component, or a support of the catch. It’s all the more however. Likewise, to the Omega 1039 wristbands, those connections are springs inside that can extend (subsequently the name Expandro) to give the watch to sit comfortably on your wrist.

Whether you’re wearing a wetsuit or not, it is anything but an issue. Jumping augmentation from the last part of the 60s, something you don’t see any longer. Unfortunately, because of their age, rust, and broad utilization, these springs will in general break, and they aren’t not difficult to fix. In any case, on the off chance that you measured the wristband right you can wear it the entire year. The growing connections, be that as it may, are just 50% of the stunt. Recall how most fastens have miniature changes where you can resize it by moving the spring bar? Doxa had a similar miniature change be that as it may, much the same as you’d have with current arm bands, you could do it by the press of a catch. There is a fastener framework inside the catch. The fasten likewise had a wellbeing press button. At the point when you press the catch in, it pulls in a tooth permitting the wrench to slide in or out. This way you could measure the clasp.

On numerous fastens, the catch is severed, so the miniature change isn’t working any longer. This is practically difficult to fix except if somebody welds another press catch to the fasten. And still, at the end of the day the usefulness isn’t ensured. Other than this the previously mentioned issue with the springs likewise happens regularly. Fortunately my arm band is turned out great. In any case, because of these known issues, I’m somewhat hesitant to wear the watch on the BoR. A third issue likewise happens regularly however I’d not consider it an issue; the wristband is an arm hair executioner. Not certain if so with everyone or I’m the just one experiencing this yet it unquestionably not a comfortable inclination to have your arm hair pulled out consistently. This could occur because of the way that the arm band is light compared to the weighty top of the watch.

History lesson

As I referenced above you can discover these Expandro wristbands with4 distinctive fasten variants. The “Doxa Sub 300” that we just investigated, two Synchron-period adaptations (with and without a circle around the Synchron logo) and one that just said “Doxa” on the catch. It’s important that Synchron S.A. purchased Doxa in 1968 and claimed the brand until 1978 (Synchron time). That year it was offered to Aubrey Fréres S.A. (Aubrey time) who in 1997 offered it to their present proprietor, the Jenny family. As a side note, in 1981 a Doxa Sub 300T on an arm band was $490. That is what could be compared to $1,350 today. Tragically, the quartz emergency didn’t just harm the watch division of the business however the adornments as well. From that point forward, the craft of wristband making vanished and with it went the Doxa Expandros too.

I’d prefer to say thanks to Mr. Andreas Gregoriades ( ) and . for their assistance with my research.
