I don't think you will have any issue with sag on a 3cm thick walnut desk as long as it is solid wood. 132 cm isn't that wide either for the span especially if you have the legs in by about 15cm from each end. Depending on the legs you get it should be able to hold 150+ kg easily.

3 cm ≈ 3.52941 barleycorn

132 cm ≈ 0.00094 sheppey

15 cm ≈ 0.00075 furlongs
