====== Nomos Alpha ======
{{wst>image_r|Nomos_Alpha|Nomos Alpha}}
**Alpha** (α) is the base [[manual winding]] movement from [[Nomos]]. It is an evolution of the predecessor [[Nomos 1 TS]] and [[Nomos 1 TSP|1 TSP]] and was produced from [[2005]] until the present day.

===== Overview =====
The [[2005]] introduction of the Alpha movement was an important turning point for Nomos. Although based on the preceding [[Nomos 1 TSP]], it was largely constructed [[in-house]] rather than being a refinished [[ebauche]]. The gear train is similar to the classic [[Peseux 7001]], but was placed in a new enclosure based on the classic [[Glashütte]] [[three-quarter plate]] design. Nomos updated many of the components, adding [[hacking seconds]], and completely reworked the finishing with [[rhodium]]-plated surfaces, [[blued screws]], [[Glashütte Stripes]], and Glashütte [[solar grinding]] or [[Langeleist-Perlage]].

Calibre Alpha was released at the same time as [[Nomos Beta]] (with [[date window|date]]) and [[Nomos Delta]] (with date and [[power reserve indicator]]). All three are hand-winding movements, as was the [[Nomos Gamma]] which followed in [[2007]]. In [[2006]], Nomos followed with a family of [[automatic]] movements, [[Nomos Epsilon|Epsilon]], [[Nomos Zeta|Zeta]], and [[Nomos Xi|Xi]], with similar features. Alpha is smaller than the others, however, at just 23.3 mm diameter and 2.6 mm thick.

This movement is officially named using the Greek letter "α", but Nomos often writes it as "Alpha".

Nomos Alpha has been used in the [[Nomos Club]], [[Nomos Ludwig]], [[Nomos Metro]], [[Nomos Orion]], [[Nomos Tangente]], and [[Nomos Tetra]] families.

Although Nomos has begun replacing most movements of this generation with replacements featuring the [[Nomos Swing System]], Alpha remains in production [[as of 2019]] with no direct replacement.

===== Nomos Alpha.2 =====
In [[2019]], Nomos introduced a version without the [[small seconds]] hand and associated gears. **Alpha.2** has the same external dimensions, decorating, jewel count, and features. It is used in the [[Nomos Tetra 27|Tetra 27 duo]], [[Nomos Orion 33|Orion 33 duo]], [[Nomos Ludwig 33|Ludwig 33 duo]], and [[Nomos Tangente 33|Tangente 33 duo]].
