The eighth Swiss team championship was directed by Dr. Robert Levi of Zürich. For the first time the competition was divided into four strength categories. Contemporary reporting counted 68 teams from 41 clubs, compared with 52 teams in 1957. The top category comprised seven clubs: defending champions SK Nimzowitsch Zürich, SG Zürich, Basler SG, SK Bern, SK Birseck, Cercle Jurassien and CÉ Alekhine Genève. Birseck were newcomers to the top division. Each club played six eight-board matches in a seven-round single round robin, with one bye per team. Match wins counted two points and draws one.

The announced round dates were 27 April, 18 May, 8 June, 29 June, 24 August, 14 September and 9 November. These were scheduled dates rather than proof that every match was played that day: Birseck–Basel in round 2 was postponed, while Bern–Alekhine in round 3 was brought forward. Both results were already reported on 5 June, without an exact playing date in the supplied clipping. The final round brought all three top-category matches together in Grenchen.

Round 1, 27 April: Nimzowitsch–Alekhine 6½–1½, Basel–Bern 6–2 and Jura–Birseck 2–6; SG Zürich had the bye. Nimzowitsch began with a convincing team victory, but Richard Schäppi defeated Swiss champion Dieter Keller on the first board. The report described Keller as having obtained the better ending before falling into a mating net. Erwin Nievergelt, Lerch, Pierre Müller, Ginsburg, Jürg Nievergelt and Tagmann won for the defending champions; Martin drew with Sudan. Basel's large victory over Bern was considered the surprise of the round. Bänninger beat Blau, and Schaffner, Leiser, Ammann, Röthlisberger and Goldberger also won. Birseck justified their reputation as strong newcomers with victories by Gereben, Leepin, Schudel, Emden and Paul Müller of Arlesheim.

Round 2: Bern–SG Zürich 3–5, Alekhine–Jura 3½–4½ and Birseck–Basel 4–4; Nimzowitsch had the bye. SG Zürich opened their campaign successfully despite Blau's first-board victory over Bhend. Christoffel, Hans Johner, Zimmermann and Baumgartner won for Zürich. Jura won the meeting of the two French-speaking clubs, with Tordion defeating Schäppi. In the postponed Basel derby, Birseck won the first three listed boards through Gereben, Schudel and Leepin, but Basel recovered through Leiser, Goldberger and Bleuel; Emden–Ammann and Fatzer–Röthlisberger were drawn.

Round 3: Bern–Alekhine 6–2, Jura–Basel 3½–4½ and Nimzowitsch–SG Zürich 3–5; Birseck had the bye. Bern's match had been played early. The Zürich derby on 8 June began at 13:00 in the Bahnhofbuffet Enge and attracted numerous spectators. Eleven Swiss master players took part. Keller lost to Edgar Walther after an oversight in an equal position. Erwin Nievergelt beat Naef, while Tagmann–Grob and Lerch–Bhend were drawn. SG Zürich also scored through Marthaler against Martin, Baumgartner against Pierre Müller and Roth against Jürg Nievergelt; Ginsburg beat Senn. With his team trailing 3–4, Martin tried to win a drawn position to save the match but lost. Basel, narrowly victorious over Jura, led the provisional table with five match points from three matches, while SG Zürich had four from two and remained the only team without a dropped match point.

Round 4, scheduled for 29 June: Alekhine–SG Zürich 2–6, Basel–Nimzowitsch 2½–5½ and Birseck–Bern 2½–5½. Walther received a forfeit point for SG Zürich; the clipping does not name an opponent for that board. Dillmann defeated Marthaler for Alekhine. Nimzowitsch recovered from their derby defeat: Erwin Nievergelt, Lerch, Ruf and Jürg Nievergelt won, while Keller drew with Bänninger and Martin lost to Basel's Paul Müller. Bern beat Birseck with Blau defeating Gereben on the first board. Leepin and Löliger scored Birseck's two wins, with Jost–Baumgartner drawn. After the round SG Zürich led with six match points from three matches and 16 board points.

Round 5, 24 August: Nimzowitsch–Bern 4½–3½, SG Zürich–Jura 5½–2½ and Alekhine–Birseck 1½–6½; Basel had the bye. The two Zürich matches were announced for the Bahnhofbuffet Enge at 13:00. One newspaper preview incorrectly listed SG Zürich against Basel; the results clipping confirms Jura as the opponent, in agreement with the original schedule. Nimzowitsch survived a close match against Bern. Keller drew with Blau, Erwin Nievergelt lost to Brunner, and Ludajic and Ruf also lost; victories by Lerch, Gmür, Ginsburg and Martin provided the narrow winning margin. SG Zürich won through Walther, Stähelin, Henneberger and Weiss, despite Johner's defeat by Straub. Birseck overwhelmed Alekhine, whose only win came from Dillmann against Müller. SG Zürich now had eight match points and 21½ board points from four matches, ahead of Nimzowitsch on six and 19½.

Round 6, 14 September: SG Zürich–Basel 6–2, Birseck–Nimzowitsch 2½–5½ and Bern–Jura 6½–1½; Alekhine had the bye. SG Zürich were reported to have fielded their strongest team for the first time. Walther, Bhend, Johner, Stähelin and Rolf Roth won, while Christoffel lost to Basel's Müller. Birseck were without Müller and Emden. Their first three boards against Nimzowitsch were drawn, after which Lerch, Ludajic, Tagmann and Ruf won for the visitors; Erny beat van Tets. Bern completed their programme with a large victory despite the absence of Blau on military service. Brunner beat Tordion, and Breitenmoser, Selhofer, Richard Meyer, Oskar Meyer and Baumgartner also won. Before the final round SG Zürich led with ten match points and 27½ board points, followed by Nimzowitsch with eight and 25. Bern had finished on six and 26½. The 18 September clipping prints Bern's board total as 20½; the 20 September report gives 26½, which agrees with the match results and final table.

The central finale took place on 9 November in the Parktheater, Grenchen, organised by Schachclub Turm Grenchen. Spielleiter Siegel and his helpers prepared the event; play began at 13:00. Eight teams were present, including Biel and Luzern for their separate promotion final. Leading games were shown on large demonstration boards, while large score displays kept the audience informed. SG Zürich needed only a draw to secure the championship, but won 5½–2½ against Birseck. Walther lost to Gereben, yet Bhend, Christoffel, Marthaler and Baumgartner won, with the remaining three games drawn. Nimzowitsch beat Jura by the same score. Keller drew with Tordion; Erwin Nievergelt, Lerch, Gmür, Tagmann and Pierre Müller won, while Ruf and Ludajic lost. Basel likewise won 5½–2½ against Alekhine to move ahead of Bern into third place.

Final standings, match points / board points: 1. SG Zürich 12 / 33; 2. SK Nimzowitsch Zürich 10 / 30½; 3. Basler SG 7 / 24½; 4. SK Bern 6 / 26½; 5. SK Birseck 5 / 24; 6. Cercle Jurassien 2 / 16½; 7. CÉ Alekhine Genève 0 / 13. SG Zürich won all six matches and took their fourth championship, following titles in 1953, 1954 and 1956. The contemporary report emphasised the club's depth: nearly fifteen masters allowed it to field eight strong players in each match. The published final table prints Bern's total as 20½; summing its six match scores gives 26½. The corrected totals across all seven teams sum to 168 board points, as required for 21 eight-board matches.

At the closing banquet, federation president Dr. H. J. Schudel congratulated the champions and honoured the Swiss team from the Munich Olympiad: Kupper, Blau, Dieter Keller, Walther, Erwin Nievergelt and Bhend. In the separate promotion final Biel defeated Luzern 5–3 and earned promotion to the first category. This match was not part of the seven-club championship and must not be added to its 168 board results.

During the season Nimzowitsch also celebrated its tenth anniversary. A contemporary article dates the merger of the original Nimzowitsch and Philidor clubs to 24 September 1948. The combined club initially used the name Nimzowitsch-Philidor, soon shortened to Nimzowitsch Zürich. Membership had grown from seventeen founders to about fifty. Its earlier team titles in 1955 and 1957, youth work and the Coupe CIRA team award at Lugano in 1958 provide context for its strong position in the championship. The anniversary match against Konstanz announced for 28 September was a separate friendly event.

Visible publication dates include 17 and 25 May, 27 May, 5, 7, 11 and 12 June, 7 July, 23 August, 18, 20 and 27 September, and 11–12 November 1958. Publication dates have not been substituted for playing dates. Full newspaper titles, page numbers and exact playing dates for the rescheduled matches remain unverified. The available local SSZ 1958 PDF is a 37-image selection, rather than the complete annual volume. Its printed p. 37 confirms the experimental introduction of four strength categories. The annual index lists championship reports on pp. 100, 121, 135, 175, 193, 216 and 236 and the schedule on p. 42, but those pages are absent from this selection. No systematic newspaper-archive search was completed. The final-round individual pairing list prints Nimzowitsch before Jura, whereas the original schedule lists Jura as host; colours require checking before PGN reconstruction. The user added SK Birseck to the club dictionary as BIRS. The reconstructed dataset contains all 168 board results, including Walther's forfeit against an unnamed opponent represented as EMPTY. Exact dates of the two rescheduled matches and several full player identities remain unknown. Colours follow the user's historical rule and the original home/away schedule, including Jura as host in the final round; no independent game scores were found to verify them. Relegation was not established from the supplied sources and has not been marked.
