====== Nomos 1 TSP ======
{{wst>image_r|Nomos_1_TSP|Nomos 1 TSP}}
**Nomos 1 TSP** is one of a family of [[manual winding]] watch movements from [[Nomos]]. Until [[2002]], Nomos simply referred to this movement as "[[Peseux 7001]]". It was produced until [[2005]] when the [[Nomos Alpha]] was introduced.

===== Overview =====
Moving from a [[Peseux 7001]] [[ebauche]], Nomos began creating their own in-house movement in the 1990's. By March, [[2002]], they gave this series a name "Nomos 1". These movements still retained the 7001 architecture and design but featured many changes and could not use the same replacement parts. For this reason, ETA/Peseux had requested that the company change the name.

The most important difference between the Nomos 1 family and the earlier Peseux was the use of [[Triovis fine regulation]]. Additionally, Nomos replaced the [[plate]] and [[balance cock]] of the Peseux with gold plated pieces decorated with Langeleist [[perlage]] at the Nomos facility. This would be the company's primary movement family until the [[2005]] introduction of the [[Nomos Alpha]].

The Nomos 1 movement family includes the following members 

  *[[Nomos 1 T]] - T = [[Triovis]] [[precision adjustment]]
  *[[Nomos 1 TS]] - T = Triovis [[precision adjustment]], S = [[hacking seconds]]
  *[[Nomos 1 TSD]] - T = Triovis [[precision adjustment]], S = [[hacking seconds]], D = date
  *[[Nomos 1 TSP]] - T = Triovis [[precision adjustment]], S = [[hacking seconds]], P = Glashütte [[three-quarter plate]]
  *[[Nomos 1 TSDP]] - T = Triovis [[precision adjustment]], S = [[hacking seconds]], D = date, P = Glashütte [[three-quarter plate]]
  *[[Nomos 1 TSDPG]] - T = Triovis [[precision adjustment]], S = [[hacking seconds]], D = date, P = Glashütte [[three-quarter plate]], G = [[power reserve indicator]]

The Nomos 1 TSP is a mechanical [[manual winding]] movement with 17 [[jewels]], and based on the Swiss [[Peseux 7001]]. The [[bridge]]s are gilded Glashütte [[three-quarter plate]], with [[Langeleist-Perlage]], the steel screws are polished and [[blued]], the ratchet and crown wheel feature Glashütte [[solar grinding]], [[Triovis fine regulation]], [[Nivarox]] 1 A hairspring, [[Incabloc]] [[shock protection]], 21,600 A/h, power reserve ca. 45 hours.
