TCXO: https://uk.rs-online.com/web/c/passive-c...cillators/
Capable of 1ppm accuracy over a temperature range without too much trouble. The best modern ones with digital compensation can get towards 0.1ppm, thus overlapping with the low end of ovens but cheaper and smaller. This was very relevant to me when designing TV sync pulse generators where 0.2ppm was needed to fully comply with the PAL standard. A bit too tight for earlier TCXOs and very loose for ovens.
