Why does gulp watch run indefinitely?

Question

gulp.js

Hello.

var gulp = require('gulp'),
  cssmin = require('gulp-cssmin'), // минификация css
  rename = require("gulp-rename"), // переименовать файл
  watch = require('gulp-watch'), // слежка
  notify = require("gulp-notify"); // уведомление 


gulp.task('default', function() {
  gulp.src(['../styles/style.css','../styles/respons.css'])
       .pipe(cssmin())
       .pipe(rename({suffix: '.min'}))
       .pipe(gulp.dest('../styles'))
       .pipe(notify("Found file: <%= file.relative %>!"));
});

gulp.task('watch', function (){
  gulp.watch('../styles/*.css',['default'])
});

1) I run "gulp watch"
2) I edit the css file in the styles folder, it runs (default) and does whatever it says. BUT it starts to repeat the execution of default again and again and again ...
Please tell me what is the mistake?

After all, it monitors changes to all .css files in this folder, you collect it, a new file is obtained - watch sees it and collects it again.
