Caliber Spec: Peseux/ETA 7001

Caliber Spec: Peseux/ETA 7001

Best Watch

First and foremost, when the world was youthful and before a chap named Perrelet began work on self-twisting movements in 1777, individuals needed to wind their own watches. Envision! No guards or wavering loads. Batteries, sun based force or active would presumably have gotten you consumed at the stake for watchmaking witchery. All things being equal, there was simply ordinary finger-power. No big surprise individuals were fitter in the old days.

It now and again feels like hand-winders have rather exited design. Yet, there are a lot of motivations to cherish a watch that you wind yourself. More slender movements, less parts to turn out badly, and no turning weight to cloud the intriguing pieces. There’s additionally the smart connection of winding your watch every morning, helping you to remember the future time and the time you’ve spent.

The ETA/Peseux 7001 is simply such a movement. Straightforward without being unrefined, it springs up under case backs from Baume & Mercier to Tissot. Junghans has their own variant, the J815, a modified ETA/Peseux 7001. Montblanc calls their 7001 the “MB 23.01.”  It even sneaks in with an Omega logo as the cal. 651 out of a progression of De Villes.

Peseux —the movement maker—took its name from its old neighborhood in the Swiss canton of Neuchâtel. Established in 1923 as a ébauche producer by nearby Charles Berner, the company was most popular for delivering our heroes—manual winders—until the dispatch of the cal. 310 and cal. 315 automatics. There are a few licenses on document for other Peseux automatics, yet the 310 and its sibling appear to be the solitary ones to have seen the commercial light of day.

Eleven years after the fact, in 1933, Berner was ending up being moresque than 215,000 movements per year. The model reach spun around a center of 15 hand winders, from the small 4 1/4 ligne loaf cal. 90 (loaves were long, slight rectangular movements that generally went in little, women’s dress watches) to the bigger tonneau cal. 110. However, regardless of this underlying accomplishment as a ébauche creator, by 1985 Peseux had gone the method of most and been consumed into ETA’s predecessor, the Ebauches SA combination .

The 7001 originally took the jump, full fledged, from the seat back in the mid 1970s and immediately acquired a standing for being dependable (as long as you didn’t ham-fistedly over-wind it), tunable, and versatile. It’s a thin 10.5 ligne movement (there are around two-and-a-bit millimeters to a ligne), with 17 gems, an Incabloc stun framework, and 42 hours of force reserve.

When Ebauches SA assimilated Peseux, they kept the “7001” classification, so you’ll once in a while see the movement alluded to as the “ETA/Peseux 7001.”

Pop the case off a watch running a 7001 and you’re struck by how basic the movement looks—particularly as nearly everybody these days is crowing about their twofold tourbillon, condition of time “bling-ographs.” Simple is, frequently, best. There are only three bridges—one for the escapement, another for the going train and the third for the heart and winding system. The movement ticks at a completely good 21,600 bph.

In its base structure, the 7001 isn’t by and large pretty—sharp edges to those scaffolds, no anglage or plating, no stripes. It’s a Ford Pinto of a movement—ugly however successful. Indeed, any less complex and you’d be hoping to see where to put the coal. All things considered, the movement takes to embellishment very well, as the numerous brands that utilization it can promptly prove.

The 7001 was planned when individuals thought a watch bigger than 38mm was somewhat profane and most likely the characteristic of a creep. It’s not just a dainty movement; it likewise has a small distance across of simply 23.3mm. This was amazing for the more modest watches famous back when the 7001 was presented, however now it’s similar to lifting the cap on a V8 Mercedes 500E to discover a Morris Minor motor and a ton of void air. The movement’s width empowers creators to deliver a slim watch, however taking the case size any bigger than around 38mm methods the auxiliary seconds dial floats in the dial.

This hasn’t halted producers getting the best use from the movement however. The robustness and straightforwardness of the 7001 make it an altogether modifiable motor — Eberhard utilized it (vigorously changed) in their 1997 8 Jours watch. Eberhard’s watchmakers cinched the 7001 to the tuning seat and figured out how to cajole eight days of force save from the little motor and even added a force save indicator.

Nomos are presumably the most popular of the 7001 tuners, however, putting together their Alpha movement with respect to it. At the point when Roland Schwertner resuscitated the old Nomos name in 1991, he expected to keep improvement costs down. Quite possibly the best approaches to do this was to utilize a set up movement.

It wasn’t until 1997 that Nomos could consider building up their own movements, so the underlying scope of Tetra, Orion, Ludwig and Tangente were fueled by a modified 7001. Nomos iterated on the base type throughout the long term, in the end dumping the three-plate course of action, leaning toward an honestly more intelligent Saxon twofold plate, adorned barrel wheels just as blued screws and Glashütte’s own personal adaptation of Côtes de Genève — Glashütter Streifenschliff — on the plates.

From 2005, nonetheless, Nomos was, in every way that really matters, , making its own movements, beginning fittingly with the Alpha. There’s little requirement for a paternity test, yet the 7001 DNA is more subtle than the movement’s appearance proposes. Without a doubt, there’s a commonality of plan, yet not very many parts are tradable with Dad. The Alpha even hacks — something the 7001 wasn’t intended to do.

In reality, until the approach of the Alpha, you might have had a Stowa Antea KS and a Nomos Tangente, both with immaculate Bauhaus plan accreditations and practically indistinguishable 7001 movements under the case back.

If Nomos went Bauhaus, Blancpain went bling. The Paudex producer gave it a genuine makeover as their Cal. 64. In addition to the fact that it got day and date wheels, yet additionally a moon-stage rather than the sub-seconds. As the Cal. 64-1, you get the entire watchmaking nine yards with anglage, a Triovis fine controller, striping, and sunburst completing on the barrel.

As the 7001 hits middle age — it’s 45 this year — what’s next? Its plain material actually permits producers an entire scope of alternatives. This little movement will take everything from plain and practical to all out bling. Also, Watchworld has a propensity for turning round trip at regular intervals. Thus, similarly as those supper plate tourbillons and complications are stylish today, such an effortlessness and tastefulness the 7001 brings might be nearly a return. Here’s hoping.
